Where you'd use it
Early Smouldering Fire Warning
Rely on the Plus Smoke's photoelectric sensor to catch slow, smouldering fires early and push an instant notification to your phone even if you're away from the house.
MQTT-Linked Safety Scenes
Use its MQTT support to trigger a wider safety scene on alarm, such as switching off a Shelly-controlled appliance circuit, since the device itself doesn't support scripting.
Long-Life Unattended Installation
Fit it in a loft or spare room that's rarely checked, since the original battery is rated for up to 5 years of use.
