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?

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..

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..

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/ )

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.

So Fitbit would redirect to..

But that doesn’t seem to work..

Any suggestions on how to do this would be appreciated..

Thanks is advance…

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..

What’s the best way to present errors to the user, and make iot clear what they need to do ?

I'm struggling to fix the code attached here

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:

The devices are created (look at line 357/410), but when I call luup.chdev.sync, they got deleted. Any hints? Thanks

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..

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)

And then the Lua file (L_****) has holds the SYCall function

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

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

I have a couple of calendar URLs I’m trying to call, and both work when i enter the URL into the browser, however when I try to call them via Lua and http(s).request, only one of them works ? Please could someone help me understand why, and what needs to be done differently to make the other one work ?

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

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

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

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

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.

and then later on within another function I see..

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.

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:

Then use it in your scene, to dynamically generate your TTS response with the device you've asked your question seconds before!

Very cool indeed 🙂

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..

Code below...

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

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!

Hi all

Here’s another snippet of code I like to use, to see what’s going on.
If anyone has any variations on this, I’d love to see it.

Sharing the love...

As I have a number of foscam cameras around the house, using their API I created the following bit of code to set to retrieve any settings across all of them, to keep them in sync.

This one gets the device name from each of them. If anyone has any variations or ways to improve the bit of code please let me know..

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.

I have a script calling io.popen to get the file system partition info, running on the Vera to check for space, and it's getting "cannot allocate memory error".

Any suggestions, beside doing a luup.reload?

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.

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:
