Embarrassing mind blank

Or course, I should be used to being blank by now.

Can someone please refresh me how I can have VeraAlexa say the value of a variable? I used to have it, but have deleted it and now failing to find it in the posts 😞

Lua - multi-part/form submission (Paperless-ngx API)

Hi

I’ve been investing a lot of time recently trying to digitise everything I can, and my current adventure is with all my paper documents.

My tool of choice is Paperless-ngx, which so far is an amazing open source solution, and highly recommended if you’re interest in such a thing…

Such a move to Paperless would not be complete without some form of integration into Vera / openLuup, and thankfully it has a nice Rest API (https://paperless-ngx.readthedocs.io/en/latest/api.html) I can use. So far I’ve been able to make use the GET requests, to provide document counts etc., but it’s the mutipart/form data piece where I’m struggling..

The Curl command to upload a document, is as follows
curl -H "Authorization: Basic Y2hyaXM62tgbsgjunotmeY2hyaXNob3N0aW5n" -F "title=Companies House File 10" -F "correspondent=12" -F "document=@/mnt/nas/10.pdf" http://192.168.102.134:8777/api/documents/post_document/
But, I’d like to know how to do this with Lua code, more just to help me in my Lua learning curve, and what I thought would be reasonably straight forward thing to do, has turned out to be quite the opposite 🙂 Sending a multipart form data submission via http.request, is not as straight forward as I hoped. If anyone has any time to help, I’d appreciate some guidance on what I’m missing with the following, as based on the feedback, it looks like it not seeing the file (which I think I’ve confirmed by trying to sending both the curl and Lua commands to httbin.org ) …
local http = require("socket.http") local ltn12 = require("ltn12") local mime = require("mime") local lfs = require("lfs") local username = "username" local password = "password" local httpendpoint = 'http://httpbin.org/post' local filepath = "/mnt/nas/10.pdf" local file = io.open(filepath, "rb") local contents = file:read( "*a" ) -- https://stackoverflow.com/questions/3508338/what-is-the-boundary-in-multipart-form-data local boundary = "-----BoundaryePkpFF7tjBAqx29L" local send = "--"..boundary..

Lua : Downloading a file over https

Hi,

I’m sure this is not a unique question about Vera (& Lua 5.1) and I’ve seen this reference in place,, but I can’t seem to find a fix to make an https download request work..

To give you an example, the code below aims to download 2 different files, the http call works fine, returning a 200 code, but the https one doesn’t, it doesn’t return anything ?

Please could some highlight what I’m missing?
print("--------DOWNLOAD http---------") local http = require("socket.http") local body, code = http.request("http://pbs.twimg.com/media/CCROQ8vUEAEgFke.jpg") print(code) if not body then error(code) end local f = assert(io.open('mnt/nas/webtest1.jpg', 'wb')) -- open in "binary" mode f:write(body) f:close() print("--------DOWNLOAD https---------") local https = require "ssl.https" --luasec local body, code = https.request("https://u.cubeupload.com/jbcooper/16146313918060.jpg") print(code) if not body then error(code) end local f = assert(io.open('mnt/nas/webtest2.jpg', 'wb')) -- open in "binary" mode f:write(body) f:close()

Luup : Fitbit API

Hi

I’m trying out the Fitbit api, not only to extract some activity data for a potential plugin, but also to learn more about OAuth 2.0. More details can be found here..
Fitbit Development: Getting Started Fitbit Development: Getting Started
You'll fit in here. Using JavaScript, CSS, and SVG, developers now have a fast, easy way to build apps and clock faces for Fitbit OS.

In addition to having a fitbit account, to get going with any integration, you need to register your app, via here..
Login
With an app registered, I’ve called mine “VERA” , I’ve written chunks of Lua code to support the various steps, (completed manually) my goal now is to try and put them all together into functions to be called in sequence on my Vera and/or OpenLuup.

Where I’m getting stuck is with the authorisation code step, which Fitbit provides appended to the domain name I registered with them when registered my app ..

Here’s an example of a redirect URL that Fitbit will redirect the user too, with their associated authorisation code, which I need in the process later on to obtain the required access token. (More specific details are here - https://dev.fitbit.com/build/reference/web-api/developer-guide/authorization/ )
https://myapp.com/callback?code=d62d6f5bdc13df79d9a5f#_=_
And it’s the d62d6f5bdc13df79d9a5f part of that new page/URL which I need..

How best do i capture/process the URL call Fitbit issues?

I assume this is where a luup.register_handler would come in, and I could register my Vera handle (using https ?, as that’s required by Fitbit) as the redirect domain/url e.g.
https://veraip:3480/data_request?id=lr_fitbit&
So Fitbit would redirect to..
https://veraip:3480/data_request?id=lr_fitbit&/?code=d62d6f5bdc13df79d9a5f#_=_
But that doesn’t seem to work..

Any suggestions on how to do this would be appreciated..
function FitbitRequestHandler(lul_request, lul_parameters, lul_outputformat) for k,v in pairs(lul_parameters) do luup.log ('fitbit_Handler: parameters are: '..tostring(k)..'='..tostring(v)) end if next(lul_parameters) == nil then luup.log("lul_parameters Table is empty") end local html = "</html><head>" .. "</head>" .. "<body>" .. "PRINTING" .. "\n" .. " lul_request: " .. tostring(lul_request) .. "\n" .. " lul_parameters: " .. tostring(lul_parameters) .. "\n" .. " lul_outputformat: " .. tostring(lul_outputformat) .. "\n" .. "</body></html>" return html, "text/html" end luup.register_handler("FitbitRequestHandler", "fitbit")

Luup : Error Handling

Hi,

Please could people share how they are presenting and handling errors in their Vera / OpenLuup plugins, I’ve tried to look through various Implementation files, but very few seem to have anything, other than perhaps a luup.task (which for some reason doesn’t work for me) ?

Below is the startup and check/validation functions for a plugin I’m working on..
function checkIPPowerSetUp(lul_device) log("Checking if parent device is configured correctly...") ipAddress = luup.devices[lul_device].ip -- check if parent device has an ip address assigned if ipAddress == nil or ipAddress == "" then -- if not stop and present error message luup.task('ERROR: IP Address is missing',2,'IPPower',-1) debug("ERROR: IP Address is missing " ..ipAddress.. " unable to progress") return false else -- if one is provided, present success message luup.task('IP Address for IPPower 9258 present, setup continues',4,'IPPower',-1) debug("IPPower StartUp activated - Device #" .. lul_device .. " now creating children") createChildIPPowerOutlets(lul_device) luup.call_delay("IPPowerPoller", 5) return true end end function IPPowerStartup(lul_device) -- set attributes for parent device luup.attr_set( "name", "IPPower 9258", lul_device) luup.attr_set( "category_num", "3", lul_device) luup.attr_set( "subcategory_num", "1", lul_device) luup.variable_set("urn:nodecentral-net:serviceId:IPPower1", "Icon", 1, lul_device) luup.variable_set("urn:nodecentral-net:serviceId:IPPower1", "PluginVersion", PV, lul_device) checkIPPowerSetUp(lul_device) log("Start up, Parent device created...") end </functions> <startup>IPPowerStartup</startup>
What’s the best way to present errors to the user, and make iot clear what they need to do ?

Vera StaticJSON Help - Showing a button’s status/selection (in/out) in the UI ?

Hi

I’m putting the finishing touches to a HDMI Matrix plugin, and while I have it working well - I can’t find anything on the Vera/MIOS wikis that tells me how I can show if a UI button is pressed or not (to reflect a input choice that is selected)

Here’s a screenshot of the child outputs I’ve created for the Matrix switcher. (The plugin creates a parent device and then 4 children to show the Matrix Outputs - parent is not shown - and the idea is that’s you select the input number for the respective output)

BB5B6001-294E-4AE9-A095-D2E639F56B9C.jpeg

Here is an extract of the button element in the associated JSON file used for the child devices..
{ "ControlGroup": "1", "ControlType": "button", "top": "0", "left": "0", "Label": { "lang_tag": "Input1", "text": "Input1" }, "Display": { "Top": 60, "Left": 50, "Width": 75, "Height": 20 }, "Command": { "Service": "urn:nodecentral-net:serviceId:SYMatrix1", "Action": "SYCall", "Parameters": [ { "Name": "action", "Value": "I1" } ] } },
The associated command calls the parent implementation file SYCall - (The value “I1” relates to a element of the URL that needs to be called to select that associated input)
<action> <serviceId>urn:nodecentral-net:serviceId:SYMatrix1</serviceId> <name>SYCall</name> <run> SYMatrix.SYCall(lul_device, lul_settings.action, lul_settings) </run> </action>
And then the Lua file (L_****) has holds the SYCall function
function SYCall (deviceNo, action, settings) ….. end

URL - /data_request?id=lu_action&serviceId=urn:micasaverde-com:serviceId:HomeAutomationGateway1&action=RunLua&Code=

I’ve just started to have a play with iOS Shortcut and one of my test cases is to see if I can do the following
select a a file (.lua or .txt) on my iPad extract the entire script/contents encode the data obtained append the encode content to the end of the RunLua action. call the URL http://myIP/data_request?id=lu_action&serviceId=urn:micasaverde-com:serviceId:HomeAutomationGateway1&action=RunLua&Code=
Below is a screenshot of the workflow I have built in Shortcuts, which seems pretty straight forward, and it does generate a encoded URL, however the actual request itself does not complete. I get an ‘OK’ response back eventually, but the code is not actioned, and the logs don’t seem to tell me anything..

The code I’m extracting from the Lua file works fine in the test Lua window, so i’m not sure what’s occurring differently, between the two routes, maybe it’s the encryption being used ?..

Is anyone able to help me test this, and see if they can generate a long / multi line RunLua encoded URL (if not via Shortcut, then by some that can help me with the root cause to then address that in Shortcut

Add-on - Aviosys IPPower 9258

Hi

Picking up from another thread this is to focus on the creation of the 4 key elements of a new Plugin for my Aviosys IPPower 9258, which are quite old, and I don’t believe are made anymore, but they seem to have a simple http api interface to cut my teeth on with a plugin.

First the device file, which is to support the creation/set up of the device, and here I explain what it is, tell Vera what the implementation file and .json file is, and also leverage the pre-existing Switch and HA capabilities..

Device File - D_IPPower.xml
<?xml version="1.0"?> <root xmlns="urn:schemas-upnp-org:device-1-0"> <specVersion> <major>1</major> <minor>0</minor> </specVersion> <device> <deviceType>urn:nodecentral-net:device:IPPower:1</deviceType> <staticJson>D_IPPower1.json</staticJson> <manufacturer>Aviosys</manufacturer> <modelDescription>IPPowerSwitch</modelDescription> <modelName>IPPower9258</modelName> <handleChildren>1</handleChildren> <implementationList> <implementationFile>I_IPPower1.xml</implementationFile> </implementationList> <serviceList> <service> <serviceType>urn:schemas-upnp-org:service:SwitchPower:1</serviceType> <serviceId>urn:upnp-org:serviceId:SwitchPower1</serviceId> <SCPDURL>S_SwitchPower1.xml</SCPDURL> </service> <service> <serviceType>urn:schemas-micasaverde-com:service:HaDevice:1</serviceType> <serviceId>urn:micasaverde-com:serviceId:HaDevice1</serviceId> <SCPDURL>S_HaDevice1.xml</SCPDURL> </service> </serviceList> </device> </root>
Next it is the Implementation file, which thanks to the feedback on this forum, will focus on a specific Lua file, where all the code will be, the only thing I need to add here are the Actions (what do I want it to be able to do etc.)

Implementation file - I_IPPower.xml
<?xml version="1.0"?>  <implementation> <settings> <protocol>crlf</protocol> </settings> <files>L_IPPower1.lua</files> <startup>IPPowerStartup</startup> <actionList> <action> <serviceId>urn:upnp-org:serviceId:SwitchPower1</serviceId> <name>SetTarget</name> <job> local url = "http://" .. ipAddress .. "/set.cmd?user=admin+pass=12345678+cmd=setpower+" .. luup.devices[lul_device].id .. "=" .. lul_settings.newTargetValue luup.log("Sending command " .. url) local status, data = luup.inet.wget(url) if (data) then debug("Data received = " .. data) else log("No Data received !! ") end local value = string.match(data, luup.devices[lul_device].id.."=(%d)") if (value) then luup.variable_set("urn:upnp-org:serviceId:SwitchPower1", "Status", value, lul_device) else log("Value returned is empty") end </job> </action> </actionList> </implementation>
The other two files D_IPPower.json, and L_IPPower.lua are still being worked on so i will add later …

Lua : storage.set , storage.get

Hi

I’ve seen storage.set and storage.get used in some Lua code posted on the internet, where they need to store/retrieve somethings, e.g.
iv = encdec.base64dec(challenge_Key) storage.set('IV', iv)
and then later on within another function I see..
iv = storage.get('IV')
It makes sense how this is meant to work, and it seems such a simple/elegant feature - hence I was wondering, is there an equivalent in Vera/OpenLuup? As I’d naturally go to use luup.variable_set and luup.variable_get - but that requires a device to be used etc.

Get your Alexa replies to the device you've asked them to with VeraAlexa plug-in

So, I was messing with my Alexa routines and ha bridge, and I want to share something very cool you could do with the ability to get the last Alexa that heard your command. I mentioned it a couple of times on the old place, but Vera's OS is missing the jq package, but openLuup could have it installed.

Basically, just execute -lastalexa with my VeraAlexa plug-in:
local lastAlexa = luup.call_action("urn:bochicchio-com:serviceId:VeraAlexa1", "RunCommand", {Command="-lastalexa"}, 666)
Then use it in your scene, to dynamically generate your TTS response with the device you've asked your question seconds before!
local temperature = 25 -- get it from your sensor luup.call_action("urn:bochicchio-com:serviceId:VeraAlexa1", "Say", {Text="Ok, outise temperature is " .. temperature .. " degree", Volume=50, GroupZones= lastAlexa, Repeat = 2}, 666
Very cool indeed 🙂

I have this block of lua and I am using luup.call_delay to delay the sending of IR codes. it works as intended but I am trying to eliminate the use of luup.sleep for the delay before the tcp:close() as well. i cant figure out how to implement luup.call_delay() for the tcp:close() and keep the luup.call_delay intact for the delay between the IR codes.

Thanks in advance.
function Delay1() --[[HDMI Matrix B1--]] local socket = require("socket") tcp = assert(socket.connect("192.168.255.204", 4998)) tcp:send("sendir,1:3,1,38000,1,69,341,171,22,21,22,21,22,21,22,21,22,21,22,21,22,21,22,21,22,64,22,64,22,64,22,64,22,64,22,64,22,64,22,64,22,21,22,21,22,64,22,21,22,64,22,21,22,21,22,21,22,64,22,64,22,21,22,64,22,21,22,64,22,64,22,64,22,1493,341,85,22,3669" .. "\r\n") luup.sleep(1050) tcp:close() end luup.call_delay("Delay1", 1) function Delay2() --[[HDMI Matrix B2--]] local socket = require("socket") tcp = assert(socket.connect("192.168.255.204", 4998)) tcp:send("sendir,1:3,1,38000,1,69,343,171,21,21,22,21,22,21,22,21,21,21,22,21,22,21,21,21,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,21,22,63,22,21,21,21,22,21,22,21,21,22,21,21,22,63,22,21,22,63,22,63,22,63,22,1528,342,85,22,1528" ..

Ok, not had much luck with the variations I tried, 😞

One thing I did notice was that the luasec version on VeraPlus is v0.4 and the openssl version is v1.0.2
# openssl version OpenSSL 1.0.2l 25 May 2017
Checking the luasec guidance here, https://github.com/brunoos/luasec/wiki/LuaSec-1.0.x , that VeraPlus openSSL version supports luasec v 1.0.x ?

Without being able to install/use Luarocks, any idea how to upgrade from luasec 0.4 to 1.0.x?

You’ll probably need to get it by hand. Ie, write a small page with some JavaScript hosted somewhere that will get the code and that you’ll have to copy and paste manually.

Never thought I’d utter these words; but I’ve been a bit prolific of late building plugins !! (9 in the last month or so )

ok, so they may not be the most elegant in design, but they all seem to work, which is the main thing 🙂

Working on number 10, I’ve returned to the error handling topic, as I’m curious about the pros/cons of luup.set_failure() vs luup.device_message()

luup.set_failure seems so impersonal and rigid (creating multi-variables) compared the device_messages - what is the value of set_failure over say a ‘job error’ red device message ?

What are peoples thoughts ?

No, sorry - that was my altered version 🙂
I had changed it from using two separate functions to just the one. I tried to do as you said, but I couldn’t see what else I could remove without breaking it ?

Yes, i think you’re right, i love how coding this sort of thing make me have to think differently 🙂

I’ve also started to add a multi_state_button too, but classic vera UI, I just can’t get it positioned where I want it too go..

83123BB1-1401-4B29-B034-9B921793BDA2.jpeg

I really want the on/off toggle button to be in line with the “Output 1” wording, and the right chevron “>”

Worse case I revert to a standard button, current .json is pasted below., if anyone can find out how to lift it up a level/row..
{ "default_icon": "../../../icons/tv_100.png", "state_icons":[], "x": "2", "y": "3", "inScene": "1", "ToggleButton": 1, "Tabs": [ { "Label": { "lang_tag": "tabname_control", "text": "Control" }, "Position": "0", "TabType": "flash", "top_navigation_tab": 1, "ControlGroup": [ { "id": "1", "scenegroup": "1", "isSingle": "1" }, { "id": "2", "scenegroup": "1", "isSingle": "1" } ], "SceneGroup": [ { "id": "1", "top": "2", "left": "0", "x": "2", "y": "1" } ], "Control": [ { "ControlGroup": "1", "ControlType": "button", "top": "0", "left": "0", "Label": { "lang_tag": "Input1", "text": "Input1" }, "Display": { "Service": "urn:nodecentral-net:serviceId:SYMatrix1", "Variable": "Pressed1", "Value": "1", "Top": 60, "Left": 50, "Width": 75, "Height": 20 }, "Command": { "Service": "urn:nodecentral-net:serviceId:SYMatrix1", "Action": "SYCall", "Parameters": [ { "Name": "action", "Value": "I1" } ] } }, { "ControlGroup": "1", "ControlType": "button", "top": "0", "left": "1", "Label": { "lang_tag": "Input2", "text": "Input2" }, "Display": { "Service": "urn:nodecentral-net:serviceId:SYMatrix1", "Variable": "Pressed2", "Value": "1", "Top": 60, "Left": 150, "Width": 75, "Height": 20 }, "Command": { "Service": "urn:nodecentral-net:serviceId:SYMatrix1", "Action": "SYCall", "Parameters": [ { "Name": "action", "Value": "I2" } ] } }, { "ControlGroup": "2", "ControlType": "button", "top": "0", "left": "1", "Label": { "lang_tag": "Input3", "text": "Input3" }, "Display": { "Service": "urn:nodecentral-net:serviceId:SYMatrix1", "Variable": "Pressed3", "Value": "1", "Top": 60, "Left": 250, "Width": 75, "Height": 20 }, "Command": { "Service": "urn:nodecentral-net:serviceId:SYMatrix1", "Action": "SYCall", "Parameters": [ { "Name": "action", "Value": "I3" } ] } }, { "ControlGroup": "2", "ControlType": "button", "top": "0", "left": "1", "Label": { "lang_tag": "Input4", "text": "Input4" }, "Display": { "Service": "urn:nodecentral-net:serviceId:SYMatrix1", "Variable": "Pressed4", "Value": "1", "Top": 60, "Left": 350, "Width": 75, "Height": 20 }, "Command": { "Service": "urn:nodecentral-net:serviceId:SYMatrix1", "Action": "SYCall", "Parameters": [ { "Name": "action", "Value": "I4" } ] } }, { "ControlGroup": "2", "ControlType": "multi_state_button", "top": "0", "left": "1", "Display": { "Top": 0, "Left": 450 }, "states":[ { "Label": { "lang_tag": "ui7_cmd_on", "text": "On" }, "ControlGroup": "2", "Display": { "Service": "urn:upnp-org:serviceId:SwitchPower1", "Variable": "Status", "Value": "1" }, "Command": { "Service": "urn:upnp-org:serviceId:SwitchPower1", "Action": "SetTarget", "Parameters": [ { "Name": "newTargetValue", "Value": "1" } ] }, "ControlCode": "power_on" }, { "Label": { "lang_tag": "ui7_cmd_off", "text": "Off" }, "ControlGroup": "2", "Display": { "Service": "urn:upnp-org:serviceId:SwitchPower1", "Variable": "Status", "Value": "0" }, "Command": { "Service": "urn:upnp-org:serviceId:SwitchPower1", "Action": "SetTarget", "Parameters": [ { "Name": "newTargetValue", "Value": "0" } ] }, "ControlCode": "power_off" } ] } ] }, { "Label": { "lang_tag": "settings", "text": "Settings" }, "Position": "1", "TabType": "javascript", "ScriptName": "shared.js", "Function": "simple_device" }, { "Label": { "lang_tag": "advanced", "text": "Advanced" }, "Position": "2", "TabType": "javascript", "ScriptName": "shared.js", "Function": "advanced_device" }, { "Label": { "lang_tag": "notifications", "text": "Notifications" }, "Position": "3", "TabType": "javascript", "ScriptName": "shared.js", "Function": "device_notifications" } ], "sceneList": { "group_1": { "cmd_1": { "label": "ON", "serviceId": "urn:upnp-org:serviceId:SwitchPower1", "action": "SetTarget", "arguments": { "newTargetValue": "1" }, "display": { "service": "urn:upnp-org:serviceId:SwitchPower1", "variable": "Status", "value": "1" } }, "cmd_2": { "label": "OFF", "serviceId": "urn:upnp-org:serviceId:SwitchPower1", "action": "SetTarget", "arguments": { "newTargetValue": "0" }, "display": { "service": "urn:upnp-org:serviceId:SwitchPower1", "variable": "Status", "value": "0" } } } }, "eventList2": [ { "id": 1, "label": { "lang_tag": "ui7_a_device_is_turned_on_off", "text": "A device is turned on or off" }, "serviceId": "urn:upnp-org:serviceId:SwitchPower1", "argumentList": [ { "id": 1, "dataType": "boolean", "defaultValue": "1", "allowedValueList": [ { "Off": "0", "HumanFriendlyText": { "lang_tag": "ui7_hft_device_turned_off", "text": "Whenever the _DEVICE_NAME_ is turned off" } }, { "On": "1", "HumanFriendlyText": { "lang_tag": "ui7_hft_device_turned_on", "text": "Whenever the _DEVICE_NAME_ is turned on" } } ], "name": "Status", "comparisson": "=", "prefix": { "lang_tag": "ui7_which_mode", "text": "Which mode" }, "suffix": {} } ] } ], "DeviceType": "urn:nodecentral-net:device:SYMatrix:1", "device_type": "urn:nodecentral-net:device:SYMatrix:1" }
I managed to get it looking roughly right on the Control Tab, see below.. but this positioning is not reflected on the main UI (see image above)

Admittedly it would be really nice if (one day) Vera could have an all encompassing http/web module

Sadly, I don't think anything new will be coming to Vera from here forward...

Thanks @toggledbits ,

I really do like the simplicity of that storage.set and storage.get .and the potential for a persistent store.

I did find some discussions on the Vera site, https://community.ezlo.com/t/where-to-store-persistent-data-from-lua/184647/2. plus I did do a quick surf and found a few examples, sadly while the first one looked promising depends on SQLlite, which I’m not sure can run on Vera.

I always know the day the cookie expires, even before MSR sends me the warning, because a very specific nighttime Rule (to turn off the screen of my Echo Spot) will fail to run, so the Echo Spot doesn't go "boop" at bedtime. 🙂

Thank you so much @akbooer , that made it work ! But what’s weird, is that I had tried various different ways too, with the following the closest to yours .
local hueenergy = require("xxhuewatts") -- lua filename/module huepower = hueenergy.getHueLight -- call lua filename/module and required function luup.register_handler ("huepower", "huewatts") -- register http handler
When it comes to the ‘syntax’ , why did it like “ GetHueLight” and not “ huepower”

Does Lua (Vera/OpenLuup?) require me to use capital letters at certain times ?

So, I've left it running all the night and it's pushing things like a pro to my MQTT broker.

Bonus points:
I've finally migrated my dashboard to WebSockets, instead of long-polling. I can't finish to press a button that the UI is updated. Brilliant! I've finally rewritten my own VeraBridge in C#, so no polling and less CPU usage on my Vera I'll probably port more things to my C# app, at this point, since I now have sub-second updates of variables I modified other parts where I was calling http endpoints from my Vera, to push UDP datagrams.
I still must find some time to fully test openLuup's MQTT broker, but @akbooer you already gave me a lot of inspiration, as always. Thanks!

Agreed, sadly I only found out about it after I’d create my version 🙂 but it was still a good learning curve, adds a total to it, and allows me to present it in the format that works for me at the time. I wonder how many other hidden bits like this are out there..
