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 ?

Under certain circumstances (thanks @DesT!) I see that it's causing a luup reload infinite cycle, because child devices are being created, then deleted. Specifically, I see this in the logs:

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..

FAB8DB5F-9003-4624-BCF3-8F536A660D21.jpeg

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

If you run the code above, only the second Google (URL `B) returns anything..

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 …

If anyone notices any improvement

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 🙂

Luup : Hue Energy (watts) Calculator

Hi all

I’ve been trying to use the Hue api and some of my Lua knowledge to create an energy calculator based on the brightness and wattage of specific models of hue bulb registered on the hub

I’ve pretty much got there, the only stumbling block I have is how I total up all the individual bulb wattages. Can anyone help ?

It’s likely an easy thing for someone more experienced to see, but as I only dip in and dip out now and then, the correct code/syntax does not always come to mind.

Note : as I’ve tried various routes, I’ve commented some things out, but you should be able to get the idea of what I’m trying to do..

Help with luup.call_delay()

Something smarter than string.format for user-defined patterns?

In my Virtual HTTP plugin I have patterns that could be specified to dynamically compose HTTP URLs based on current values. So, if you enter
http://myip/color?v=%s

it gets replaced with the current color. It's very handy when having more parameters, or if your parameter is in a different position.

The problem is that from time to time, there are users with legitimate % in their URLs (since it's the escape char in URLs, after all) and this is causing weird behavior or crash.

So, I want to find something smarter to support both.
Any hints here is appreciated.

List of plugins available at the Alternative App Store

A

The plugins listed here are available via the Alternative App Store. The app store becomes accessible via a new menu item in the Alternative User Interface once configured.

Both the Alternative User Interface (AltUI) and AltAppStore (AltAppStore) plugins need to be installed on Vera to access the store. With openLuup; this is all "automatically" set up and ready to go as part of the openLuup suite.

The Alternative App Store can be found here.

Publishing a plugin in the store is pretty easy. First your plugin code must be available in GitHub. Publish it, using the Publish command in the AltAppStore web page. You need to enter the salient information and it's ready to go.

Plugin icons can be stored on GitHub eg like so. After a "few days" the raw json describing the plugin appears here.

Vera 3 users should note the store will not work, as Vera 3 doesn't have the https capability required to access GitHub. However, the apps can always be downloaded from GitHub and manually installed.

For those just interested in what the store contains; refer to the list below - as of 2021 July 27 there were about 75 plugins available:

How to parse JSON path in LUA?

Hi,

I'm working on new features for my Virtual Devices Plug-in. One of the things I want to add is the ability to poll an endpoint to get power consumption.

So, I want to store the URL and the JSON path in a variable, but I'm confused on how to dynamically parse JSON paths in LUA.

I have something like this in a string variable
data.meters[1].power
and I have to extract the corresponding value from the JSON I got over HTTP.

Any suggestion is very appreciated. Thanks.

Humidity/Mold sensor

I'm trying to write a sensor similar to this:

home-assistant/core home-assistant/core
:house_with_garden: Open source home automation that puts local control and privacy first - home-assistant/core

I've already translated it to LUA, but I'm getting strange values. Maybe it's because it's not that cool yet.

Anyone has already done something similar? I have outside and inside sensors and I want to run my de-humidifier based on certain conditions. I want to avoid condensation on the large windows. Last year I ran it based on a fixed threshold, but I want to optimize this if possible.

I've implemented this:

https://smarthome.community/topic/20/openluup-version-log/18

into my own MQTT Server and that's cool, since I'm now pushing every variable via MQTT, originating from the Vera.

Just a couple of questions for @akbooer
- do I need to check that sock is connected, from time to time?
- is there anything specifically to retry the command?
I'm running it in the latest hour, and everything seems OK, but I want to code it for the worst situations. Thanks, always inspiring!

@therealdb said in UPD Datagrams:

No, because there is no permanent connection formed in UDP. If you look on the console System > Server page you can see that it always appears unconnected:

@therealdb said in UPD Datagrams:

is there anything specifically to retry the command?

Again no (if you're meaning that in the context of sending a datagram) becuase there is no way of knowing whether or not it failed to arrive.

How have you selected ALL your Vera variables? (Simply an exhaustive list of possible services?)

@akbooer thanks! I've obviously included as many serviceIDs as I know. so far, so good!

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!
