I tried just doing an install of the interface from HomeGenie using the downloaded zip file from github on my pc. I did not try to do a reset back to factory first - to be honest, at this point I'm out of time and patience today.
Tried toggling the interface on and off (Disable / Enable) both with the IP address and without - no luck. Icon appears when its Enabled, but its always light gray (and in the instructions in the original text file I see mention of the light gray icon, it scrolls off the screen which is why I had not seen it earlier). So something still is not right.
For now I have it Disabled, and I connected to the Pi via Putty and started the HA Bridge service (and that is running again). Pulled up the Alexa page and did a Discover and all my devices are there again.
I have some time again tomorrow to mess around with this, but will see how things go in the morning. If the only real way to get it working is to do a backup, factory reset, install the interface again, etc I may try that tomorrow. For now, I am back to the Alexa commands working but taking some time and replying with the device not responding (even though it works).
Thanks for your patience and your assistance, I do appreciate it.
