I used to have this rolluik switch that I will call Screen. https://nl.aliexpress.com/item/33052311020.html?spm=a2g0o.order_list.0.0.21ef79d2SSmCej&gatewayAdapt=glo2nld It was connected to the Tuya Cloud and the app in Homey. Till then it worked fine. Than the Screen was broken so I ordered a new one. By the time that one was delivered and mounted on the wall and I installed the switch to the new screen, Tuya had changed their Tuya Cloud Platform.
I also have two double roller blinds that I added in the Tuya Cloud a while ago. They work fine.
I managed to add the Screen switch to the Cloud as well and I can control it with the SmartLife app on my phone. When I add it in the Tuya Cloud app in Homey I can add it but the Screen doesn’t do anything. No error nothing.
Removed the screen in Homey, restarted everything, tried it with the local Tuya app. Nothing helps.
