I have a MPPT solar charge controller that I built from an older Instructables project. Works great, uses an ESP32. The code was written to send data to Blynk, and there was a link to the template the author created for monitoring and control. Unfortunately, Blynk changed their platform since then and the template is “invalid”. I want to be able to integrate it into HA. The current Blynk platform only shows 4 data streams and thinks they are switches. I’ve tried modifying them to see what data they contain, and they only seem to want to display 1 or 100 on any of them no matter how I configure them.
The device itself is actually writing 17 different items to Blynk. I’m tired of wasting my time with Blynk. I want to directly monitor the data with HA. It does provide a stream of serial data from the USB port. The HA is in the house and positioned for my RTL-SDR to pickup my gas and water meters, so I don’t want to move the Pi5 running HA to the garage. Is there a way to send that serial data through the USB port of a pi in the garage then over the network to the HA? Would that be a remote MQTT broker or something else?
Any assistance appreciated
And here is what the serial data looks like. I am wanting to capture #'s 1,4,5,6,7,9,11 and 12
