dzVents 1.1.1

[dannybloe]

For those interested. I just released version 1.1.1 of dzVents with a couple of fixes and additions:

[1.1.1]

• Added support for a devices table in the 'on' section.
• Added extra log level for only showing information about the execution of a script module.
• Added example script for System-alive checker notifications (preventing false negatives).

[1.1]

• Added example script for controlling the temperature in a room with hysteresis control.
• Fixed updateLux (thanks to neutrino)
• Added Kodi commands to the device methods.
• Fixed updateCounter
• Added counterToday and counterTotal attributes for counter devices. Only available when http fetching is enabled.

Nice!

I will give it a try tonight.

Just a thought.
Might it be an idea to have a variable setting(s) in dzVents_setting.lua for alternative paths for the http fetch file and the storage files?
I then could put them on a tmpfs. It prevents the sd-card for too many writes.
I already optimized my whole system this way.

[dannybloe]

good idea

[Eduard]

Very nice! Thanks for all the good work.

One thing that's bothering me is that i stil have issues when the httpdata is fetched. I think it has to do with the great amount of devices i have that fetching them via the httprequest is taking a long time.
It might be an issue that the script whats to acces the devices.lua file while it is still being created by the httprequest.

Maybe it is a good idea to fetch the devices to a tempfile and then rename it after is has finished. In that case the (previous) devices.lua is still available for the script to read, while being fetched at the same time.

[dannybloe]

Yes, I have noticed that too. I will try to implement such a scheme.
Hopefully we can get by the need for this http stuff really soon. I see it as a temporary thing (/me looks at giz... )

I noticed these too, but usually (cannot say with 100% certainty) they happen on the hour xx:00, which coincides with the hourly backup. So I figured that the file is for a brief moment not accesible and thus causing the error

[dannybloe]

I'll try to implement it today or so. Shouldn't be too hard.

[dannybloe]

I added support for this in the dev branch. Can you please test it? It now uses a tmp file first when downloading the json and only when it is done writing it copies it over to devices.lua.

Thanks! Seems to work. Not getting errors until now. Will continue to test the next days...

Still getting issues with the dev-branch ;(

Is there a beginners tutorial for dzVents anywhere? It looks so useful, but I've no idea how to get started. I've read the wiki, but I'm still stuck on how to get started. Any guidance for a LUA newb?

Not completely sure it is related to 1.1.1, but setting the level on a selector switch does not work anymore.

No errors, and nothing happens. This script used to work before.

return  {
  active = true,
  on = { ['timer'] = 'every minute' }, 
  execute = function(domoticz)

        local sonos_name = 'Utomhus, Sonos'

        local status = sonos:read('*all')
        sonos:close()
        local jsonStatus = json:decode(status)
        
        playerstate = jsonStatus['playerState']
        if (playerstate == nil)
        then
            playerstate = 'OFFLINE'
        end

        if (playerstate == 'PLAYING')

            domoticz.devices[sonos_name].level = 10

I think it is because you are not using any of the update methods on a device . You cannot do device.level=xxx. In your case you could use the switchSelector(level) command or the dimTo(level) command. Both result in a 'Set Level xxx' that is sent to domoticz.

Lemme know if that works for you.

Are you talking about a tutorial for Domoticz events in general or using dzVents? For the latter, if you follow the installation instructions you are about 80% done .
Then it's just a matter of creating one or more script files in the scripts/lua/scripts folder. There are a couple of examples in the dzVents folder that may get you started.

So assuming you have Domoticz up and running, got at least one switch (or a dummy switch) created and you installed dzVents to the proper location you can look at dzVents/examples/respond to switch.lua. That's a simple script that will respond to a switch being turned on. Oh, and it sends a notification so you may have to configure that in Domoticz as well.

Works perfectly fine, missed that method (switchSelector) when reading the docs. I´m a .net developer, so that kind of justifies that I tried to set a property in that way

Yeah, I don't think Lua supports this kind of attribute manipulation. (If it does, I'm not gonna change it anymore anyway )

Latest dev-branch is error-free now for the last couple of days

[dannybloe]

Well, it swallows that specific error. Did you check the logs because when it does I print a message.

[dhanjel]

Forgive me If I have missed something, but is it possible to set the security state of the house/system from the scripts?
