I’m looking into smart radiator thermostats, and the Aqara thermostat E1 (zigbee) is on top of my list. I know that it’s possible to connect it to an external aqara temperature sensor via the Aqara Home app/hub. However, I don’t want to use the app, I would like to provide the external temperature v…

Hey! I`m using the “Better Thermostat” and on my side it has problems with turning the Aqara TRV back to hvac_mode “heat” when it was in “off”… What settings are you using? I have it connected over Zigbee2MQTT. I can set everything over the HA UI, but using “Better Thermostat” does not work for me…

I am using Better Thermostat as well and i can say that when the TRV is “Off” it still keeps the Target-Temperature… really strange. I think it isn’t a problem with Better Thermostat, it’s a Problem of the TRV itself. But i am not 100% shure…

Yes, compared with Moes, Aqara TRV is good and works as expected.

Hi, thanks for sharing, now my TVR read right temperature. I’m a beginner in HA (supervised) and i have a question i use 5 aqara TVR with z2m and i pilot gas heater by a sonoff mini zb several automation for TVR,shedulating time, temperature etc… but only time schedule for sonoff switch the sist…

Everything is working well compared to Moes TRVs. :slight_smile:

I’m trying to set this up, and I can easily publish the sensor data to the right topic (well, I can now once I learnt some more about MQTT). But how do I decide when to publish? I basically want the TRV to always use this sensor when it’s “looking” at the temperature. Will it automatically look at t…

TRV should be set to use the external sensor and you should publish the room temperature every time it changes. The rest is done by the TRV. I have a node-red automation that publishes the room temperature as soon as it changes. You can also implement this via the native HA automations.

Ok that makes sense, I’ll look into that. But one thing I’m wondering is that the room temperature changes the whole time no? I mean it’s got 2 decimals, so that changes every few minutes. But I guess that’s normal behaviour then?

From my own experience it doesn’t change that often. I have also limited my sensors to a single decimal from z2m, but I guess you can apply some other sort of filtering as well. Also, I don’t think that the TRV will react to minor temperature changes.

Turns out I’m not yet there with publishing my data to the TRV… I can get the temperature showing in debug in Node Red, but seems I’m having trouble publishing it to the right topic. I can do it manually by typing in the topic and using the mqtt.publish node in Node Red, but there should be a way t…
