Is it possible to add the "Sensors API" definitions to the bridge? If we could add a virtual sensor, you could set up triggers for routines within Alexa that could do fancy Alexa things... like announce stuff. I'm not sure if the bridge (pretending to be a Hue Hub) can only use devices that Hue makes or can different device types be added in?

Either way... an overdue congrats on the bridge. Mine has been running stable for a year or two without any major issues. (I have to disable my PLEX server whenever I add/discover new Alexa devices)
Lastly... if this is a dead end. Do you know of any work-arounds? I was toying with the idea of creating virtual wemo devices. But I can only find write-ups to make them into virtual outlets running on a raspberrys. (not exactly what I'm trying to achieve)
