Can confirm, the metal spray guns are way better than the disposable cans. Their ‘reusable’ disposable cans had poor flow and kept clogging on me.

Why eat bugs when you could eat lentils?

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.

It’s a good idea, but at this point I’m too frustrated to wait a few months to see if the moved alarm does or does not go off. And then I’d have to figure out what’s different and how to fix it.

Right now I’d rather spend some money and get smarter alarms, if they’re available.

FYI, there is a Scheduler card that might make that automation easier.

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?

I’ve had 10 of the RGB ones, E21-N1EA, for a few months now and they’ve been working perfectly. Not the brightest or the most accurate color, but they’re simple, cheap, and local-only.

Have you checked out Frigate? It’s a local service that captures RTSP streams from cameras and uses neural net image recognition to trigger events / recordings. It has good integration with Home Assistant.
