So I know I have read on forum the MCT-320 does not work, but the MCT-340 does. I don’t have an xfinity MCT-340, but that doesn’t make sense to me. I’m wondering if it’s any door/window sensor from xfinity? According to Visonic there is not much difference in the MCT-320 vs MCT-340 but they made the MCT-340 low profile.
They both pair the same with the xfinity device and show up the same.
I have close to 20 sensors on every door and window in my house, all MCT-320. It’s the only stuff left paired to my xfinity hub for home security. I would love to use them.
I have an extra MCT-320 and I was able to pair it and set it as an MCT-340, but the red light on the MCT-320 just kept blinking. I tried to use the magnet to complete the pair like you do on the xfinity iControl unit, but no luck. It just shows as always open in SmartThings.
I haven’t pulled the source of the MCT-340 yet and done any debugging, but at looking at the system logs when I paired as an MCT-340, I saw nothing come across the logs, so either no good debug outputs in the MCT-340 code or nothing was happening.
Any ideas if this is just a total dead end?
