I had this problem before. If I set the Controlled by setting of any A/V template to my GC-100 and restart LMCE, the A/V template disappears. The GC-100 serial port works fine for my Insteon PLM, but none of the IR outputs work anymore either.
Does anyone know which logs might help me troubleshoot this problem? Or can I simply delete the GC-100 config and recreate it (hopefully without having to redo the Insteon PLM template)?
Any help would be appreciated.
