Node Red: Relais on Smart Solar

Hello,

I would like to control a heating rod in Node Red. To do this, I would need to use the relays from two Smart Solar. Everything should actually fit in my Flow, but I can't switch the relays. Do I have to make a presetting in the devices themselves, as I have to do with the Cerbo (setting: Manual)?
Or is it because the Smart Solar are currently "Off" due to the lack of solar input?
Or what could be the reason that the relays do not switch?

Greetings from the Ambergauer

Hi @Der Ambergauer @Metz Producties


I use shelly smart switches to achieve this. Use http node to activate the smart switch. Relatively affordable and then dont have to be place close to solar as long as they're in wifi range/on same lan

Hi @Metz Producties

There's a load of ways depending on what you need it for.

Personally I just use it for turning things on and off. I dont really care about recording data in victron system (I use openhab for that). so i just use NodeReds http node to send on/off command.


If you want to monitor the load being used i think there's a custom driver you can install for that:

You can use this node: https://flows.nodered.org/node/node-red-contrib-relaycontrol Which offers support for several (network connected) relay control boards.
