ESPHome implementation to pull data from BT-enabled Renogy devices
-
renogy_batteries.yaml is configured to connect to a single Renogy BT device (currently tested on a BT-2 connected to five batteries in a daisy-chained configuration.) There are TODOs in the yaml that indicate places where updates should be made, or at least pertinent information for the user is available.
- renogy_battery_utilities.h contains methods to do the payload creation and response parsing for communicating with the BT device. This file shouldn't require any editing in order to get things running.
-

If you don't yet have any experience with ESPHome, I recommend looking here for guidance: https://esphome.io/guides/getting_started_command_line
I use the command line to compile and upload my configurations to my ESP32 board(s) and therefore don't have any experience with the ESPHome web interface (glancing through the docs, I don't know how to use header files like renogy_battery_utilities.h that are used in this project, so the CLI is probably your best bet.)
Here are instructions to install ESPHome manually (which is what I did.) https://esphome.io/guides/installing_esphome
Once that is done, you can run commands such as these from the root of this project:
esphome compile renogy_batteries.yaml # (compiles without uploading, so you can test your changes without needing a board connected)
esphome run renogy_batteries.yaml # (compiles and uploads to a connected board)

- The original Renogy BT project - This current project is effectively a port of cyrils' work to make it run on ESPHome. None of this would be possible without the groundwork that was laid there.
