DzVents cannot find device but it is there

[elgringo]

So I have a sensor:

And a dzvents script:

Code: Select all

local sensorBuiten = "Temperatuur buiten"
local sensorBuitenBackup = "Temperatuur buiten tuin"

local sensorExtern = "KNMI - Temperatuur"
local sensorExternWind = "KNMI - Wind"
local sensorExternAlarm = "KNMI - Weeralarm"

return {
  on = {
    --timer = {'at 6:00'}, 
    devices = { sensorExternAlarm },
    timer = {'every minute'},
  },

  execute = function(domoticz)
    local lastUpdate = domoticz.devices(sensorBuiten).lastUpdate.minutesAgo
    local lastUpdateBackup = domoticz.devices(sensorBuitenBackup).lastUpdate.minutesAgo
    local tempLokaal = -999
    
    if (lastUpdate < lastUpdateBackup) then
      if (lastUpdate < 30) then
        tempLokaal = domoticz.helpers.round(domoticz.devices(sensorBuiten).temperature, 1)
      end
    else
      if (lastUpdateBackup < 30) then
        tempLokaal = domoticz.helpers.round(domoticz.devices(sensorBuitenBackup).temperature,1)
      end
    end
    
    local tempExtern = domoticz.helpers.round(domoticz.devices(sensorExtern).temperature,1)
    local tempExternGevoel = domoticz.helpers.round(domoticz.devices(sensorExternWind).chill,1)
    local alarm = domoticz.devices(sensorExternAlarm).text
        
    if (tempLokaal > -50) then
      domoticz.notify(tempExtern.."C ("..tempExternGevoel.."), lokaal "..tempLokaal.."C", alarm, domoticz.PRIORITY_LOW, nil, nil, domoticz.NSS_FIREBASE_CLOUD_MESSAGING)
    else
      domoticz.notify(tempExtern.."C ("..tempExternGevoel..")", alarm, domoticz.PRIORITY_LOW, nil, nil, domoticz.NSS_FIREBASE_CLOUD_MESSAGING)
    end
  
  end
}

It complains that it cannot find the "KNMI - Weeralarm" device. Changed it with a id (761) but this also does not work.

Code: Select all

Line 32 is: local alarm = domoticz.devices(sensorExternAlarm).text

How is this possible?

[hestia]

have you just create your device?
or it is an old ones?
restart domoticz to check again...

[elgringo]

Device was rather new a restart did the trick

[hestia]

what hardware / plugin?
Anyway it's not normal...

[roblom]

DzEvents always need a restart in order to be able to read it is my experience.

[hestia]

I've never seen this except recently with a specific hardware /pluging ; that why I'm asking with what hardware / pluging you experienced this behaviour.
@roblom, it seems that's it for all the hardware you've got? A lot of ? If not which ones?
@elgringo, which hardware please?

[roblom]

I've had this in the past several times but can't remember which specific hardware that was. I thought the last time it was with a Fibaro wall rollershutter which was added with mqtt ad.

I'm just perform 2 inclusions test
1 with a zwave MQTT Autodiscovery: a power plug Neo CoolcamVersion: 2022.2
1 with a ZigbeeForDomoticz: a motion sensor Sonoff SNZB-03
the test was with 2 scripts: DzVents et LUA
I had errors at the beginning (not sure I've forgotten to set "Set Used" or a rename, or a delay), but in the end, both LUA and Dzvents were ok for both devices without restarting dz!
Some time ago I had this issue with ZigbeeForDomoticz
but it was another version of dz

Code: Select all

Version: 2022.1 (build 14305)
Build Hash: 67f94077d
Compile Date: 2022-04-05 13:18:48
dzVents Version: 3.1.8

now

Code: Select all

Version: 2022.2
Build Hash: eea9db734
Compile Date: 2022-11-05 13:05:35
dzVents Version: 3.1.8

and I also changed the ZigbeeForDomoticz version...
and it was with a temp sensor

So for me it is the normal behavior to have the device available after inclusion w/o restarting dz!
