Hi, and thanks for the quick response.
I tried the roll back but found that the Lolin S2 Mini was not an option in that version. I tried the Wemos D1 ESP32 and it would compile but the upload failed "Chip is unknown ESP32".
I am going to try and use an external FTDI to avoid issues with USBCDC. If that does not work I will just use the D32 module.
Thanks for the great body of work and support. I cannot even imagine how much work it must be to try and cover all the different chips and modules.
The integration with Home Assistant makes this a breeze!

Thanks for the quick response.
Yep! When I updated the IDE I forgot to modify the settings (915 MHz) in the new myconfig.h file.
Doh!
All good now.
