  • The storage capacity is sized for daily consumption, not the yearly figure you quoted. And of course, this is one small project out of the hundreds of plants that will be needed to meet climate goals.

    The biggest issue with solar right now is that the output varies over the course of the day, leaving other power plants to take up the load at night or during cloudy weather. The attached battery storage averages out the solar plant’s output, letting it be a useful contributor to the grid around the clock. There’s other benefits like grid stabilization and peak shaving, where the battery stores and releases oversupply from the rest of the grid, not just the attached solar panels.


  • 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?
