Kevin, confirmed that it is version 1.7.4. Attached is a screen grab of the rest of the version command output.
Things that seem to be correct:
1. WebApp SW version (I installed your image without change)
2. AD2Pi wiring (I am getting messages from the Vista P20
3. Keyboard address setup
Most likely remaining issue: WebApp config. I have tried just about every combination I can think of...
