I recently installed new electric shutters in our house. I believed the salesman who claimed the shutters could be easily controlled via phone or LAN.
It turned out, they are not. They are controlled via the Tuya Smart Cloud. Usually Tuya devices can be easily with Tasmota. But I could not find anything about how to flash theses devices. On the other hand flashing would also be just a last resort since I do not want to potentially destroy my blinds.
You have to use the Tuya cloud to make the devices available to openHAB. Local control will most likely be possible after that, but that isn’t true in every case. After you connect it, deny your blinds Internet access and then see if you can control them.
More information is available on Github.
By the way, if you’re using OH4, the instructions for adding SmarthomeJ to openHAB are slightly different.
