He long well he doesn’t block against the corners. He goes all over the room.

I have motorized a 3 shutter in which I will do it and I already bought all the material, it has been very easy to install this switch, with the control and connect it with the app to the Wi-Fi all at the first attempt, in this case I also placed the engine on the left side, That come prepared for the right, but through the app I was able to make the change without problem, the end of the race must be done manually with the tool that attaches the engine, not through the app, but everything great and the aesthetics of the switch I really like with the lights.
