Where you'd use it
Behind-switch scene triggers
Fit it behind an existing multi-gang wall switch so the physical buttons keep working while their presses trigger scenes on other Shelly relays instead of switching a local load directly.
Low-voltage panel integration
Wire it into a 5-24V DC control panel so existing momentary buttons can fire HTTP or MQTT actions on other smart devices in the system.
Layered multi-click actions
Use the up-to-12-action multi-click support so a single input triggers a different scene depending on whether it's pressed once, twice, or held.
