Today I will present to you the connection that I am going to implement. In short, the customer has a GoodWee + inverter with a contact that can turn on the boiler, but it is unimaginable to pull cables through the houses.
Sonoff provides huge possibilities so why not use them? The picture shows how I’m going to connect it.
Steps:
1 Monitors whether S1 and S2 are connected.
2 If it is connected, the zbb-p gateway knows about it.
3 Turn on the socket to which the boiler is connected.
It is necessary to set the scheduler to turn on the Sonoff s60 socket at a reasonable time so that there is always hot water.
I chose the s60 socket because the customer has no other options and wants to see the boiler consumption.
