Hello guys. 
I’m not using the home assistant app, but mi home only. I have reached a point from where I can’t find a solution. I would like to use aqara wall switches to make smart lights and also to control my external shades. With lights they work perfectly but shades are the problem. I need to program the switch not to be able to have left and right button turn on at the same time. To explain. I need a function, when I activate the left switch button to first turn off the right switch button, and then turn on left, and oposite. When I do this with mi home app, it simply doesn’t work. It seems it looses conection and sometimes it activates left and right side at the same time. Is there someone here who could help me?
Anyone? :))
