FWIW, I was able to get 3 HA input_boolean’s discovered and added to Alexa by creating a separate bridge for each of them, using ports 5540, 5541, and 5542. Even then I had to nuke and re-create the bridge several times before the “There was a problem” message went away. After setting up, the states don’t sync very well – HA->Alexa direction seldom syncs and while Alexa->HA direction mostly syncs, the state on Alexa side sometimes does not reflect the true state. In any case, it’s a great integration - thank you @t0bst4r !
