Esphome definitions for Growatt Wifi-X stick with SPH1000-TL3-BH-UP. This should work with the whole range of those SPH inverters 5000-10000,
This is a simple yaml to flash the Growatt Wifi-X stick with esphome to replace the slowly updating cloud so that you are actually able to use Home Assistant.
As I needed to do a lot of digging and could not find a working one for my SPH, I hope you will find this works for you in case you find yourself in a similar situation.
This has most sensors added and working, you can switch between battery, grid or load First and enable AC charging. Setting (dis)charging limits is also possible.
With adjusted uart ports this probably will also work with a serial converter and regular esp32 connected on one of the RS485 ports.
Leave a star if it works for you, and pull requests are welcome too!
