Done! Using this tutorial. Don’t have a rooted phone, so used a combination of the Rooted Android Device & Bluestacks method. Short of it:
- Do not install and connect the Magnum Heating app!
- Download an older Tuya’s Smart Life app (see Youtube link above)
- Use the Smart Life app to connect your thermostat to your WiFi
- Install Bluestacks on a PC, root it, etc.
- Install that older Smart Life app on Bluestacks as well
- Log in with the same Tuya account
- You should be able to copy the relevant files (containing device ID, but more importantly the file with the LocalKey) from Bluestacks to your computer and find the LocalKey
- Install the LocalTuya integration for HASS from HACS
- It will discover the thermostat from your network, just fill in the found LocalKey, et voila!
It’s read-only for now I guess? Since “climate” is on the ToDo for the Local Tuya integration. So I’m using Local Tuya to read data only for now…
Maybe this helps someone!
