I have a garage which is 25 meters away from our house. I plan to charge the battery of an ebike in this garage. On top of the garage I have a PV-system. This is why I am looking for a smoke sensor in this garage, that I can integrate in my home assistant installation. So it has to work under stronger conditions than inside the house. Temperature can be between -10 C and +40 C.
For connection I do have ethernet cableand an AVM Fritz Repeater/Access Point for WLAN inside the garage. So I am relativly free, to add any system… any suggestions? THX!
