Hi,
there's one major issue in all the smart home platforms I know:
Motion sensors break manual actions. For example, if I manually activate a light switch, the motion sensor still starts the automation to turn the light off after x minutes. Of course you can check "if light is off", but there are scenarios where this simply doesn't work as intended.
With 3rd party Hue apps, you actually can disable and enable Hue's motion sensors, which works better. Still not perfect.
I'd like to make the suggestion to implement a function into Tuya to override automations by manual button presses. Motion sensors or automations then shouldn't have any effect on overridden lamps. This would make things a lot easier.
