Implementation not working with smart solar / serial

[Henschga]

Hi

I recently switched from the bluetooth to serial implementation which works fine for the smarthsunt, but not for the smartsolar products. After triggering the script manual I can see that there are missing dependencies to the library but this should be working (as it works with the smartshunt). Is there any advice that you can give me?

Since I ran into the same issue here's how I fixed it.
The mappings.py in ./lib seems not to be up-to-date and simply does not contain a representation for some newer devices.
In your case you just need to add a line to the PID = {} section containing "0xA07D": "BlueSolar MPPT 75/15 rev3", and the script should be working.
