Saswell Tuya Wi-Fi Heating

Hi

I’m a newbie to HA and Home Automation in general and I’m 73 years of age and been working with things Computer for 52 years now so forgive me if some of my terminology is a little dated.

I don’t think Saswell have a concise name for this system and it is sold on Amazon as

SASWELL TUYA WiFi Heating TRV Radiator Thermostat with Hot Water Control,Smart Radiator Thermostat, Dual Channel Wireless Receiver(Starter Kit), Compatible with Alexa, Google Assistance.

and comprises an SASWG-04-RF-WIFI(TY) Gateway, a single SEA802-DF TRV and an SAS2016DE2 Receiver. The receiver is effectively a 2 channel switch turning on and off the Central Heating and Water Heating functions of the boiler.

The system does work (though certain components appear to go on and offline randomly) but its implementation in the SmartLife app is extremely poor and I would say unstable.

In addition 2 this I also have a single SmartHome smart breaker which is wi-fi controlled.

Tuya recognises all these components in both SmartLife and in the IoT Platform but when I add the Tuya integration, only the TRV’s are discovered and the SmartHome breaker and the Saswell Receiver are not brought across. Conversley when I add Local Tuya only the Gateway and the Smart Breaker are discovered and if I try to add the Gateway I get the error message .

Failed to authenticate with device. Verify that device id and local key are correct.

The Smart breaker does add in properly

Am I doing something wrong or is it that the Saswell Gateway and Receiver are not implemented in Tuya Local

Can anyone help please

Hi, have no idea with gateway, but you can use zigbee2mqtt to integrate directly the TRV in HA. Then add it as climate and you can control it. I bought 10 pcs stand-alone last week, without Hama zigbee gateway, and integrated them all without problem in HA.
