So I’m finally getting a chance to look through the new firmware on the OpenEVSE and setting up the items in there I want to utilize. As soon as I get my solar installed (I’ll be installing it, already have the Schneider Inverters mounted and partially wired) I’ll get Shaper back up and running as I loved that back at my old place. But now I see Vehicle which looks like a way for the EVSE to talk with the vehicle. I see the option for Tesla, but also MQTT and HTTP. I was wondering if there was any documentation for how to use those. I have an EV6 and a BMW X5E (hybrid), but am not sure where to start or if there was documenation for the OpenEVSE on how to use MQTT or HTTP.
Bueller?
I guess I wonder. Does the OpenEVSE read that back from the vehicle and the MQTT is just a way to send it back to EmonCMS?
No, there’s no way for OpenEVSE to read the SoC from the vehicle, unfortunately two-way communication is not part of the J1772 protocol. The MQTT topics are to provide the OpenEVSE with a SoC reading. The SoC reading will need to be obtained and posted to MQTT via other means e.g manufacturer cloud API, OVMS etc.
Ok, that’s what I was thinking WRT J1772. Have to look into how to pull those from the vehicle, if possible. Thanks, answers the questions I had.
