I give credit to @jnick for discovering this bug.
I did a quick search for this but didn’t find anything dealing with the Phillips bulbs and bridge.
ST v2 hub, 1st generation Phillips bridge, Phillips hue and lux bulbs (1st & 2nd gen bulbs), Amazon echo
ST and hue bridge integrated via hue connect smart app. ST and Hue linked to Amazon Alexa in Alexa app and in the ST app.
Bulbs are paired to the hue bridge. They are authorized for use by the ST hub. They are NOT authorized for use with Amazon echo from within the ST/Alexa smart app.
The bulbs are controllable by Amazon echo via the Phillips/echo link within the actual Amazon Alexa application.
Turn on/off Phillips bulb via Amazon echo. ST app takes up to five minutes to update the status of the bulb.
Amazon echo is still able to turn on/off, dim, and otherwise control the Phillips bulb regardless of the status of the bulbs within the ST app.
I have personally seen this but did not realize what the problem was until tonight. When a hue bulb is turned on/off via Amazon echo and a ST routine/rule/function is activated within a shirt time if the bulb state change; the Phillips bulb will not respond properly.
Failed routines and dissatisfaction
I have not developed a rule machine work around at this time, I am working with @jnick to find one. I will post the resolution in this thread once found.
@slagle is this a known bug? Is there a repair in line?
I am submitting all of this to support.
