Dear all,
I would like to monitor my camper in homey. I can use the victron VRM to see aal the data but I would like to have the data in my homey for logging and monitoring.
It imust be possible to send data using Node Red on the cerbo GX and then read it on homey. Anybody ever tried this and can help me on some tips?
Next week I’m fitting the cerbo in the camper. I might figure it out. But I know a lot of you guys might be able to help me.
thanks in advance
Can you “translate” the “what you have” and “what you’d like” in sort of a scheme?
Cerbo gx (node red) send data to homey
Retrieve the data using webhook.
Found Using Webhook with Node-RED • FlowFuse how to create webhooks on node red do i need Authentication?
It’s ffinally working. Red node is now sending data which Homney catches. Took me a long time to figure it out.
In node red you create a variable using the change Node.
The function creates rhe webhook using:
var SOC = flow.get(“SOC”) || 0; // Haal de opgeslagen waarde op
msg.url = https://webhook.homey.app/<homey-id>/SOC?tag=${SOC};
return msg;
Then de Request node is method=GET and URL = empty
(the inject node is purely for testing)
