2 motion detectors and 1 mailbox sensor quit working

my motion detectors worked fine when i first installed them then they quit working. I tried taking the batteries out and re installing them with echo 4th gen plus hub

Hi there, @Jayirvinh! Checking battery connection was a great step to take. Please also ensure they are charged sufficiently for operation. I recommend bringing the devices inside near the Echo (4th Gen) and wifi router to see if connection will improve. Feel free to let us know how this goes! :slight_smile:
