Im trying to make Cerbo GX aware of my grid comsumption measured by a third party meter.
I amgetting the power consumtion into node red perfectly fine, but how can I map this so Cerbo GX use this as the power meter reading?
I was thinking of MQTT, but I would need a little help where to start.
Hi gr1pen,
i have setup a Raspberry Pi with Venus Os ans use this script from Mr. Manuel
https://github.com/mr-manuel/venus-os_dbus-mqtt-grid
because i dont want to install a EM24.
I read the power consumtion out over IR Reader Head ( Volkszähler, Hichi ) to node red.
The Payload need the format:
msg.payload = {"grid": {"power": msg.payload }};
return msg;
then i subscribe the topic on Venus Os.
This works for me Perfect!
Now i have ordered a Cerbo, and trying this in few days. :-)
Hi,
I am trying to do something similar, but I don't find the topic to which I should publish the message. Could you point me to it? Thanks.
