Scrapes the HTTP endpoint of a Solax X1-Boost G3 with PocketWIFI v3 firmware and pushes the scraped values to an MQTT server. Other inverter models are available but I only have access to this one.

Most of the data for this project came from squishykid/solax.

Configuration is currently done by editing the source code and recompiling.

PocketWIFI is dreadfully insecure. Use Modbus-RTU or, at the very least, a PocketLAN, if you can. I'll be switching as soon as I'm able to.

The PocketWIFI squirts MQTTS to their cloud servers, but they don't verify TLS so it can be trivially intercepted. However, the messages are in a useless (to me) binary format.

Once the metrics are in MQTT, they can be sent to prometheus using mqtt2prometheus:
