Thanks Geddy, I think you’re right. But I’m glad to know about Universal Devices. I’ve always wondered when someone would solve for IoT not working without internet connectivity. Great to have stumbled upon this. Take good care!

| Universal Devices hub Thanks for the welcome! I'm not sure which type it is, but I did find that the electricians had turned off one of the light switches into which my Philips Hue hub was plugged. (I used to have it in a non-switched outlet, but because of absolute chaos during renocations it got moved ... a lot.) So, finding the Philips Hue hub off, I turned it back on and *nearly* all the Alexa bulbs came back on with voice activation, through any Alexa device. One group of three bulbs in a midcentury lamp ("Jetsons Lamp") is still misbehaving. I have deleted and then have run discovery again, and found the individual bulbs (that mysteriously kept their names: Jetsons 1, Jetsons 2, Jetsons 3). But the group Jetsons Lamp may need to be recreated. I'm not that techie with smart home things, but generally I am pretty savvy and mechanical-minded. What else should I try?

I found this forum searching Google for the phrase "Sorry the hub ... is connected to is not responding, please check the network connection...". The previous thread, archived now, showed up in my search. And those things are not working for me. Alexa.amazon.com now shows a QR code directing your phone to download the app. (I did discover my app could use an update, so I did that. Unrelated to the smart home device requests.) Does anyone have more up-to-date advice? We did have electricians here rewiring things. I added a new hanging lamp over my kitchen island and used the same Alexa smart bulb in it that I had in the light fixture we replaced. The electricians were tripping breakers purposely, to make sure they had the right things labeled correctly at the panel. Still, none of this seems at all relevant to the smart bulbs all at once not working. The hub the kitchen light connects to is my Echo Plus. It's either on or it's unplugged. It runs software updates automatically. Any bright ideas? (wah wah wah wahhh)
