  • OP here, I ended up purchasing one USI MI106S, which advertises the following:

    • Combines the benefits of both Photoelectric & Ionization technology in one alarm
    • Smart Alarm Technology virtually eliminates nuisance alarms
    • Automatic temperature and humidity compensation continuously adjusts to variations in environmental conditions, reducing nuisance alarms

    Which sounds like what I’m looking for. I’ll try some informal tests on it before I buy more.





  • I’ve got a T6 Z-Wave also, controlling a 2-stage heat pump. I have it connected to HA through Zwave2mqtt. It’s been pretty great except for two things:

    A. Changing the time has no effect, as if the clock is read-only due to a hardware issue. I’ve had to set up the daily schedule in HA instead, but it’s probably better that way anyway.

    B. I can’t see the stage and aux heat status in HA. Looks like all it exposes is a ‘heating’ or ‘cooling’ state. Anybody know how to get more info?
