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..

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!

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.

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.

Sun position or light sensor for blinds?

I have finally integrated my new motorized (blackout) blinds in the home office, since I'm planning to mainly work from home at least since the end of the year.

I'm quite satisfied, since I made them completely automatic, but I noticed that I have two problems:
rainy days: I have a rain sensor for the exterior sunscreens, so I can think about moving the interior ones as well moving season: while moving them to a middle position for the night is good now at 30 minutes before sunset, I'm not sure it will be OK in autumn or winter.
So, I was thinking about adding some logic linked to sun position, or a light sensor device.
Any hints, before re-inventing the wheel? Thanks.

I also have a preset function loaded in my startup lua to directly send post commands to my home assistant instance which I posted here:
https://smarthome.community/topic/39/lua-function-in-openluup-startup-lua-to-send-async-command-to-home-assistant-api

which then enables me to create a variety of scenes triggered by the site sensor: For example disarming the site sensor docks the roomba by creating a variable watch on the arm status of the site sensor and then run this code:

Likewise I can get it to start cleaning from openLuup through a similar scene

And you can let wild of your creativity from there... I have an identical integration for the xiaomi robot and am tuning the vacuum noise according to whether I am on the same floor while the robot is cleaning...

Help with luup.chdev.sync

I'm struggling to fix the code attached here

dbochicchio/vera dbochicchio/vera
LUA Scripts for the eZlo Vera Platform (UI7). Contribute to dbochicchio/vera development by creating an account on GitHub.

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:
2020-06-01 19:35:30.482 luup.chdev.sync:: [102] Open Sprinkler Test, syncing children 2020-06-01 19:35:30.482 openLuup.chdev:: deleting [413] Daily Garden 2020-06-01 19:35:30.482 openLuup.chdev:: deleting [414] Water Level 2020-06-01 19:35:30.482 openLuup.chdev:: deleting [411] Daily Cedars 2020-06-01 19:35:30.482 openLuup.chdev:: deleting [412] St-Eustache Rules AM 2020-06-01 19:35:30.482 openLuup.luup:: device 102 'Open Sprinkler Test' requesting reload
The devices are created (look at line 357/410), but when I call luup.chdev.sync, they got deleted. Any hints? Thanks

Virtual Rain Sensor using Site Sensor and Weatherbit API

With all the acquisition of Dark Sky by Apple in the plans, I thought I would share my rain sensor setting which is used as input for my irrigation system:
Install @toggledbits site sensor Register for a free tier account from http://weatherbit.io an pick up the API key the url I use is using forecast over 2 days (replace with your coordinates and key): https://api.weatherbit.io/v2.0/forecast/daily?lat=**yourlat**&lon=**yourlong**&key=**yourkey**&days=2 The trip expression is as follows as I also pull a variable from within the sensor variable for the calculation: tonumber(response.data[1].precip)+ tonumber(response. data[2].precip) + tonumber(getstate( 67, "urn:toggledbits-com:serviceId:SiteSensor1", "PastRain"))> 5 For display I also pull these value expressions: "Total Rain "+(tonumber(response.data[1].precip)+ tonumber(response.data[2].precip) + tonumber(getstate( 67, "urn:toggledbits-com:serviceId:SiteSensor1", "PastRain")))+" mm" "Tomorrow "+response.data[2].precip+" mm" "Today Probability "+response.data[1].pop+"%" "Tomorrow Probability "+response.data[2].pop+"%" response.data[1].precip "Today "+response.data[1].precip+" mm" "Accumulated "+getstate( 67, "urn:toggledbits-com:serviceId:SiteSensor1", "PastRain") Add a time based scene with the following lua code to record the past day rain accumulation every night at the time of your choosing (I use 23:00). Replace the sensorid variable with your sensor id) local sensorid=**yoursitesensorid** local siteid= "urn:toggledbits-com:serviceId:SiteSensor1" local current =luup.variable_get(siteid,"Value5", sensorid) luup.variable_set(siteid,"PastRain", current, sensorid)
With this, my yard irrigation only turns on when the sensor is not tripped... meaning less than 5mm of water is accumulating across 3 days (yesterday, today and tomorrow). Adjustments in value can easily be made.

UDP Datagrams

Code/Snippet library

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:

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!
