Could you check if this change from strstr to strcmp makes any difference to your TPMS Jansite-Solar fix at all.

It shouldn't really, but best to double check.

I copied the changed code into my platformio workspace with the actual development branch, compiled and tested the creation of my TPMS sensor. It's still working as expected!
