Hello 😃 I have replaced all 3 old Aqara hubs with the new M1S version. He added the whole sensor again and everything works great. But there’s one thing I didn’t figure out how to set up … using old hubs, I was able to connect the hubs together in case an alarm happens, so all the sirens can warn me. (one hub per floor). I didn’t find this setting using Mi Home with M1S hubs and also if I test it by activating night mode and opening a window, only the paired siren gets loud … any idea?
