How to use HY369 TRV in openhab

Setup, Configuration and Use Items & Sitemaps

Hi folks,

I thought, it seems to be a good idea to buy four TRVs in China. :blush:

Now I´ve received them and try to add in in my openhab system.
But there are some problems I can´t solve.

First issue: After the device was added to my zigbee network the time/date changes to Sunday, 6:28 AM. It seems, the device awaits date and time from the gateway but on wich channel?

I´ve discovered the device with mosquito_sub and find the following channels:
TRV_zigbee_device.txt (2.8 KB)

I wondering that there is no battery info.

Next Problem: I don’t know how to figure out which channel can be written to change its state/value.

I tried this for the setpoint:
Type number : setpoint "Eingestellte Temperatur" [ stateTopic = "zigbee2mqtt/HeizThermo_Office/current_heating_setpoint", commandTopic = "zigbee2mqtt/HeizThermo_Office/set/current_heating_setpoint" ]

But nothing changes on the device if I change the value at ‘Basic UI’.

Has anybody an idea to solve my problems or maybe uses the devices already?

Regards,
Heiko

Your log says

...HeizThermo_Bad...

But your openHAB configuration says

...HeizThermo_Office...

They need to be the same!

Your are right but I uploaded the wrong log.
Of course log and configuration uses the same names.
I can read the values, so that is not the problem.

We can only advise on the information presented to us!

In that case, I would forget about openHAB for the minute and try to directly control the TRV via MQTT, either continuing from the command line with mosquitto_pub and mosquitto_sub clients, or perhaps a more user friendly client like MQTT Explorer or mqtt.fx. Once you’ve satisfied that what you want to see and do is possible, then come back to openHAB!
