That's the official link: http://www.becaenergy.com/index.php/Home/New/productsinfo/id/59.html
My version is GC

Did not remember where, but i've found, related to that device, the attached "API"
API (1).zip
But can't find "thermostat ID" to start communication

Maybe it's protocol version 3.3? A pull request just went in to support 3.3 based on the javascript code in the tuyaAPI repo
