Bought a Dome Siren a few weeks ago and it connected great. Installed dome device handler and have had no problems.
I got a Neo Coolcam Siren Alarm (looks same as Dome) and cannot pair the device to Smartthings.
Reset the device…held button for 10 seconds.
Tried to Exclude the device (would not excude)
Tried to Pair (Add) the device 6 inches away
unplugged my smartthings v2
Nothing seems to work. Any advice would be appreciated.
