Finding PowerPal bluetooth address

G'day mate,

Thanks for your great work, I have gotten this going and it is working a treat.

For the benefit of others, I just wanted to point out that unlike your example esphome yaml skeleton, my powerpal lives in a bluetooth address space of F9:D1:0F:00:00:00 rather than the DF:5C:55:00:00:00 address space mentioned.

If you are another punter like me trying to get this to work, and your powerpal does not have the bluetooth address listed on the device or on the packaging, an easy way to find it is to stand near the powerpal with an android phone and add a new bluetooth device. You'll see "powerpal-somethingblahblah" appear. Connect to it, and then once that is completed, view the connection. The bluetooth address is listed.

Additionally, if your computer is close enough to the powerpal, just flash the esp32 with this repo's code and the esp32's local console will display blue output from "esp32_ble_tracker" which will list detected bluetooth addresses. My computers were nowhere near the PowerPal, so I found using an android phone easier.

Once again, thanks for making available your work so the rest of us could enjoy it, you're a top bloke.

Cheers.

ESPHome Compilation Errors (example yaml) with ESPHome v2022.12.3

Using the example powerpal_ble.yaml, and ESPHome v2012.12.3 (simply changing the board from "wemos_d1_mini32" to "esp32dev")- the Install compilation consistently fails with errors relating to the ble_tracker.cpp component and in incompatible return type.

ESPHome yaml file and compile log are attached.

Is this a possibly a breaking change in the ESPHome core framework since your powerpal_ble component was devised? I'm sorry that I'm new to ESPHome custom components and framework source code, so I can only report to you what I'm encountering - not sure what code changes might resolve these errors.
