Where you'd use it
Consumer unit boiler switching
Install on DIN rail inside the breaker box to switch a boiler or heating circuit via the dry contacts without running any extra cabling to the panel.
Ethernet-reliable relay control
Use the LAN connection for a relay controlling something critical, like a gate or a pump, where a WiFi dropout during a control command isn't acceptable.
Webhook-driven automation
Trigger the relay via an HTTP webhook from a separate monitoring script or third-party system, for example switching on a pump when an external sensor reports a condition.
