Visonic mct-427 is not pairing with ST

any advise to pair visonic mct-427 with ST

isn’t compatible with SmartThings

seem that many products are not compatible…i will try with wink hub 2

I don’t think you’ll have much luck getting it to work with Wink either. Just like the other sensor you asked about, the majority of the SMC and Visonic zigbee devices sold with cable company security systems (Xfinity, Cox, Time Warner, etc) use an encrypted proprietary version of the zigbee HA protocol, and aren’t compatible with anything else.
