Hoping this one may be simple, it’s been implemented on the ESPhome project and pretty well documented here: GitHub - WeekendWarrior1/powerpal_ble: Collection of code, tools and documentation for data retrieval over BLE from your Powerpal
if it were possible to add compatibility with this device it’d be great, as the compatible version of ESPhome isn’t capable of doing it via the boards I own, and I’d prefer to stick to one solution for all my devices.
Also may make it a good use case to attract users, as there are a fair number of Australian users of this device looking for ways to retrieve the data.
