I called alexa stupid yesterday and next thing I knew, I was having problems with most of my alexa devices.
what happened was, I told alexa to turn on television, she did, then I asked what the temperature was in here, and the response was television does not support that. I asked several times and kept getting the same response. got tired and asked if alexa was stupid and the response was to file a feedback report. Looked in history and alexa heard me correctly.
I did file a feedback report giving a detail explanation of the problem. the response was them asking for a detail explanation of the problem. basically I quit. got the survey and said terrible on everything. right after that nothing was working properly and had to do a power cycle on all of my wemo switches and had to do a discover. maybe it was just coincidence but...
sorry got a bit sidetrack.
for the fun of it, I just asked if kitchen light was on. It turned it on. just asked again, like you, alexa does not support that. And like you, google told me it was off. surprised alexa does not support this feature. sure would come in hand when you have smart home lights and devices in other locations.
