OK, I have run out of ideas and memory cells. I set up my somewhat extensive system 8 or 9 years ago with +/- 100 devices, voice commands, programs and such. Its an ISY994iZW/IR Pro. I week or so things went south and I eventually installed my new back up PLM. I now have communication with the devices but hte amazon voice control does not work. Echo's acknowledge the command but nothing happens. The 'hard coded' scenes (programed to a physical button) work fine so it seems like its just hte echo voice interface. My memory on that stuff has aged out - any pointers?
