Sonoff and Goodwee

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.

I have done similar and In addition I have used sonoff basic switches to modify dumb zone valves to be smart.

There are many options. I have another customer I’m going to do this for, so maybe there will be photos too.

Hi, Sonoff ZBMINIL2 does not have a dry contact.
Did you connect ZBMINIR2 directly to the photovoltaic?
Is it not a problem that the voltage is going that way?
So far I have only used Sonoff MINIR2 which is on WiFi for status monitoring dry contact.

I use contacts s1 and s2 to monitor the closing status of dry contacts on the Goodwe inverter.

Yes, I understand, but there is voltage there, 230V, isn’t that a problem?

That’s a dry contact, there’s no voltage there, it just closes the contact.

Thanks, that’s great news. I haven’t seen that anywhere in the documentation. I’ll try…

Narazal som na Sonoff ZBMINIR2 a suchy kontakt. Vyuzivam ale WiFi verziu, kde MINIR2 bolo aj farebne odlisene (siva svorka).

V minulosti som si vsimol, ze pouzivas ZBMINIR2 na spinanie (rozne projekty), nerozumel som preco, uz viem.

Robis zaujimavu robotu.

To je jedno či je to wifi, matter alebo zb. Sleduješ len či je kontakt zapnutý na meniči. Takže použijes S1/S2 ( suchý kontakt na goodwee ) a napájanie pre modul.

Dá sa stoho urobiť obdoba wattrouteru. Lacno a hlavne to funguje.
