Alexa is having occasional difficulty with one of the skills I use. I have a TP-Link multi-colored LED lightbulb that is controlled by their TP-Link Kasa skill. Periodically it simply quits working through the Alexa skill, though it still works fine through their app on my iThingies. I went to turn off the light last night and Alexa said the device was not responding. It turned right off with the app though. It is strange that the skill would periodically quit working for a brief time (usually just a few hours). I think perhaps TP-Link is updating the skill or Amazon's Bezos Bozos are messing up the FW for Alexa when they push out updates. I know TP-Link has sent a few emails explaining that there was an issue and then another after it is fixed, so it is probably on their end. BTW, they never did manage to get all the functionality into the Alexa skill, so TP-Link definitely has some programming issues on their end. Frustrating.
