I’m trying to set up a security system for my Mother-in-law, so I bought the above siren some motion sensors and tested them with my existing system. I then bought another V2 ST Hub and now have that working and set up with new motion sensors. I tried to un-pair the siren from my existing hub. Ended up selecting Forced removal (sorry about the misused terms) and now I can’t get the LED on the siren to blink to connect to the new Hub. Tried pushing the the tamper button in the back 1 sec, no effect and 7 sec which set off the alarm.
Thanks for any help.
