Thanks Michiel, I recently ordered the same unit with the plan to modify it to make an alarm for a cool room door, having a delay before it sounds, then falling back to send off a message if no one responds, your internal photos show that this should be possible.

Thanks for the inspiration! I ordered a bunch and post my progress soon.

Would it be possible to fit a pro mini in the one you linked in the BOM, or is that another case?

@antonholmstedt a pro mini fits if you cut the corners, check out https://forum.mysensors.org/topic/6612/door-sensor-remix-of-some-mys-community-efforts
