Hi and thanks for reading.
I have my Open EVSE up and running great in standard mode.
Now I am working to set up the PV divert.
What MQTT messages need to be sent to get PV divert to function?
I do not have an open energy monitor, but I do have a system set up and monitoring current/voltage.
I can't seem to find the exact MQTT messages needed to get the Open EVSE to see available current to charge.
My connections are most similar to a "Type 1"
But, my EVSE is connected at the "junction block," so that current isn't seen by either current sensor.
Ideally, I'd just send my calculated EVSE wattage. But, I can't find the documentation for what is needed.
You are in luck, OpenEVSE needs available power in watts.
Send your calculated watts available to the MQTT topic of your choice, subscribe to that topic with OpenEVSE and enable eco-mode.
Thanks for the information.
It took some playing around, but it looks like the topic may need to be #/mqtt_solar
I had tried multiple different combinations of topic names, this one worked.
