Zigbee switch switches "spontaneously" off

[mknops]

Hi,

I have a Phoscon Conbee 2 (firmware 26720700) happily functioning on my RPI (on buster) running Domoticz 2022.1. My setup is fairly simple, having a couple of LED lights that I switch on and off manually or through timers in Domoticz using both RFXcom and Zigbee. I am not using any scripting.
One of my switches is a Robb Smart Switch which I actually not use to switch but to measure the energy consumption of my hybrid heat pump. Domoticz however every now and then seems to decide to switch it off, thus stopping my heat pump. First I thought I had accidentaly hit the switch in Domoticz, but after having it password protected and it switching off at 04:32 this morning (while sleeping of course)....that cannot be the case.

Here is the full log of the switch itself in Domoticz:

My questions:
- what does (the device?) RFXcom have to do with it?
- is the March 11 event different than the March 10 event......?

Domoticz status log:
2022-03-11 04:32:30.309 Status: Notification: Warmtepomp aan-uit >> OFF
2022-03-11 10:21:08.008 Status: User: mknops (IP: 192.168.1.39) initiated a switch command (2609/Warmtepomp aan-uit/On)

(The March 10 status log event looks similar, I have unfortunately purged it before safeguarding)

My question:
- since the March 11 log shows a notification for the switch being in "off"-modus. Could this event be triggered by the physical Robb Smart switch itself? The switch is, by the way, not overloaded, the power load on the heat pump is quite low actually (<1kW).

Domoticz error log:
- empty

Any other places in Domoticz, Deconz or Raspbian where I could look for clues?

Any help is appreciated!

Kind regards,

Michel.

Hello

Could this event be triggered by the physical Robb Smart switch itself?

Yes, you have en entry "puch switch" on the device if I m right, you can use it to make test.
If for a reason or other, the device turn off, it send a notification to prevent of his state (it's zigbee report).
what is your zigbee plugin ? It's better o look in the plugin logs to see if it' a request from domoticz, or a return from the device.

This kind of logs mean an action on domoticz to the device.

Ok, thx, I will check the DeConz logs too.
As you can indeed see from the logs I manually switched the heat pump back on but left the logs entries to show here, for your reference and to contrast the not so well understood log entry.
