Dear All

I'm tryning to use z2m with tuya HY368 smart radiator valve, i follow the instruction on the wiki page but when i try to publish with mqttexplorer the message on zigbee2mqtt/FRIENDLY_NAME/set the message for comfort temperature and for eco temperature nothing happen, the temperature value deosn't change

{
"comfort_temperature": 21
}

{
"eco_temperature": 21
}

for other parameters works fine

how i can solve?

thanks in advance for your help.

Hi,

I have the same Tuya valve, and I used mosquitto_pub/sub to look what was happening with my mqtt messages.
Not sure how you concluded that the temp value doesnt change, but you might want to change current_heating_setpoint.

e.g.
mosquitto_pub -h localhost -t zigbee2mqtt/0x60a423fffeab4b8a/set/current_heating_setpoint -m "17.5"

eco/comfort temps are used in presets eco and comfort. (whereas a normal preset is "schedule" when using a weekly schedule)
not sure if these are visible through UI of valve itself...

Hope this helps,
R.
