i bought this aqara U400 from amazon in the US as i wanted UWB but during installation my carpenter messed up a bit and now i have this really thin of an exposed antenna cable which is not working. I’m not even able to connected this to the Aqara Bluetooth app the clock receiver power and the front lits up but no connection i haven’t tried matter yet tho. Is there any way to fix this, where can i order a replacement for the antenna cable that ships overseas ? or is there a place i take this to get it fixed ? really need some help here guys.
