What data does Tuya HA integration collect and send to server

Hi all,

I want to use the Tuya integration in HA. However I don’t trust Tuya folk (or similar cloud based IOT entities) the least. I want to isolate the wifi controlled heater in a separate iot (wifi)network and use an defunct android device to connect the heater to the network. After that the Android device will be turned off again.

The last unknown is the Tuya HA integration. Is it possible for the integration to collect (sensitive) data and send it to the Tuya servers? Or does it only retrieve data and send commands?

Anyone has an idea?

Thanks!
