FAQ

Can this relay switch mains power?
No — it’s intended for low-voltage control via dry contacts. Use a qualified electrician and suitable interfaces for mains loads.

Will it work if the internet goes down?
Yes — control scenarios run via the hub; external notifications depend on the hub’s connectivity.

What happens on power loss?
You can set a fail-safe state (open/closed) or last-state memory, depending on site policy.

Does it need a separate power supply?
It requires 12 V DC, either from your system PSU or a dedicated low-voltage source.
