Where you'd use it
Hidden Retrofit Relay
Fit the Plus 1 behind an existing switch to add app and voice control to a garage door, curtain motor or radiator circuit that was never wired as smart.
Dry Contact Security Interfacing
Use the dry contact output to interface with an existing gate or alarm system that expects an isolated switch rather than a live relay.
On-Device Scripting Without the Cloud
Write a custom script that runs locally on the device, so basic automation logic keeps working even if the internet connection drops.
