Any ideas how to install since balcony door is sliding into frame?

Hello @dmmatic, can you place the sensors a little bit higher than attach the adhesive on the back of the sensors to the door frame and door so it is stable?
Tape it up with some easy to take off tape and try it. I tried it with one of mine and it works that far apart in that arrangement.
No - what I’m writing is that you don’t HAVE to have contact.
I think they can be up to 3/4 inch apart.
Pleased to see it worked. And thanks for reporting back with pics.
