I have my heat pump in the Android app “Tuya Smart Life” and successfully integrated it into Home Assistant. However, only on/off and heating target temperature are available.
Can anyone tell me if and how I can get more data? Can I set the target water temperature? Can I read sensor data?
Thanks and best regards
My heat pump: Thermatec TH-R290 S06-1P
(Ich habe meine Wärmepumpe in der Andoid App “Tuya Smart Life” und diese auch erfolgreich in Home Assistant integriert. Es stehen jedoch nur an/aus und Solltemperatur Heizung zur Verfügung.
Kann mir jemand sagen, ob und wie ich noch mehr Daten bekomme? Kann ich die Soll-Wassertemperatur einstellen? Kann ich Sensor-Daten auslesen?
Danke und viele Grüße)

No, I didn’t manage it with the Tuya Cloud. But I did with Modbus.
A device was already installed: Elfin-EG41B RS485 ↔ 4G&BLE. I replaced that with Elfin-EW11A-0 RS485 ↔ Wi-Fi. If none is present, it belongs on COM2.
And now, with a little Modbus magic, at least these things are possible:
- On/Off (also worked via the cloud before)
- Mode (cooling, heating, hot water, …)
- Operating mode (normal, boost, silent)
- Hot water temperature adjustable and actual temperature visible
- Heating temperature adjustable (but unfortunately the actual temperature is not yet visible)
Furthermore, various voltages, currents, frequencies, temperatures… They’re there, but I don’t need them.
Attached are a few pictures and automation yaml

Nein, mit der Tuya Cloud habe ich es nicht geschafft. Aber mit modbus.
Es war schon ein Gerät verbaut: Elfin-EG41B RS485 ↔ 4G&BLE. Das habe ich ersetzt durch Elfin-EW11A-0 RS485 ↔ WLAN. Wenn keins vorhanden ist: Es gehört an COM2.
Und nun, durch ein wenig modbus-Magie, sind mindestens diese Dinge möglich:
- Ein/Aus (ging vorher über die Cloud auch)
- Modus (Kühlen, Heizung, Warmwasser, …)
- Arbeitsmodus (Normal, Boost, Silent)
- Warmwasser-Temperatur einstellbar und Ist-Temperatur sichtbar
- Heiz-Temperatur einstellbar (aber leider noch nicht Ist-Temperatur sichtbar)
Weiterhin noch diverse Spannungen, Ströme, Frequenzen, Temperaturen… Sind zwar da, aber die brauche ich nicht.
Anbei ein paar Bilder und Automatisierungs-yaml
