I’m running it on a DS918+ right now. I copied-pasted their docker-compose file and had it up in half an hour or so.

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.
