I just added two Intermatic InTouch CA3750’s to my IQ4. I bought them because they are on the compatibility list and the only devies that will do what I’m trying to do. Which is control a compressor, electric heat, and multiple outdoor lights.
Anyway, they are supposed to have two separately controllable sets of contacts. However, it only shows up as a light switch so you can only control one set of contacts. Making this nothing but a very expensive and impractical light switch. Since it is on the compatibility list for the IQ4 panel that would mean it’s fully compatible.
Alarm.com unfortunately does not support multi-relay switches. It may be able to be used as a DPST I believe where both are triggered simultaneously, but it will only show up in Alarm.com as a single switch.
If a Z-wave switch has multiple relays or functions, generally only the first will be available in Alarm.com. We’ve requested support for multi-relays and scene controllers quite a few times.
Yes, the vast majority will work given their simplicity. Most report the same parameters in the same way.
There can be exceptions. Avoid Cooper switches. If you find something you might want to use, check the model number on our support forum here to see if there are any reports about it.
