This is awesome, getting this part figured out would be a huge help to getting the protocol working reliably! I will try to get some time to try the modified...

I've not been able to get the modified app to run :( I get the brief initial splash screen, then a blank screen. Logcat shows the following: ``` - waiting...

Here's the registration debug log: [phev-registration-debug.txt](https://github.com/buxtronix/phev2mqtt/files/9689253/phev-registration-debug.txt)

[phev-update-debug.txt](https://github.com/buxtronix/phev2mqtt/files/9704857/phev-update-debug.txt) [phev-parkinglights-debug.txt](https://github.com/buxtronix/phev2mqtt/files/9704858/phev-parkinglights-debug.txt) I've attached two more debug files.

First thing I discovered...a client can 'deregister' itself by writing the value `0x01` to the register `0x15`. I learnt this by sniffing the OEM client and selecting the 'cancel vin...

I connected phev2mqtt (using an unregistered mac address) to my car when it was in registration mode, and whilst it was then able to do the usual fetch of registers,...
