Have tested this multiple times - only the first added BUTTON works, on a bridge.
Other devices (LED etc) can be on the same bridge and have multiple instances working, but only one button - additional ones just do nothing!
I noticed the pin chosen for the second button does not get set as a pull-up (noticed by measuring, I'm not good enough at coding to find it in the code!).
I also get "accessory out of compliance" when trying to add the bridge when it contains the button....I can add the bridge and later add the button OK though.
