We just purchased a home with ISY and UD, this is a large amount of information for me to understand, we had a garage motion detector battery die and i replaced it, with no look with it connecting t the network. I tried "link management" "Link Sensor" "Motion sensor II" I selected "add devices found in links and keep existing links" typed in the same numbers from previous and no dice. the funny thing is when i do that and press beep it beeps. it is so weird. thanks your help.
