Not sure if other had this issue so posting and hope it helps
I am now able to consistently pair emulated Hue devices to Alexa using below.
This required NO config Kung Fu or trickery.
1. Verify descriptor file is present at http://<HA IP Address>:8300/description.xml (means Emulated Hue running)
2. Restart HA from Developer Tools (this stops Hue)
3. Wait for descriptor file to be available at http://<HA IP Address>:8300/description.xml (means Hue restarted)
4. immediately attempt Alexa Device Discovery when descriptor file loads (when Hue starts)
It seems that Alexa is only able to discover devices when emulated hue is first started
Devices may show as “offline” if you run Alexa discovery again, but they still work without error
Yes. Once the page loads, immediately press the Discover button in the Alexa app. If possible, press right before the /description.xml page loads. Sometimes you need to try few times before it is successful.
Can anyone confirm if this method still work? Even killing the HASS process and restarting doesn’t work for me. I even tried removing one of the existing devices in the Alexa app, but cannot rediscover anything.
I don’t mean to dig up an old thread but just want to put this here incase it helps anyone down the track.
I had my Raspberry pi3 plugged in with Ethernet to an old router directly hooked into my main modem over Ethernet, Decided to retire the router and use a D-link Ethernet switcher instead.
A few weeks later noticed in Alexa devices all said “Offline” but everything turned off and on as expected but nothing new added could be found, After trying all tips in this thread I gave up and just left it… Then It came to me that maybe it was the switcher!. So I plugged the Pi into the old router again and low and behold everything is appearing online .
So I can confirm (on my end at least) that it was a network issue of some sort.
I would say it’s better here than as a new thread without the historical info for reference
A few people with the same problem have eventually ‘admitted’ to changing routers ‘around the time it happened’ but for some reason won’t see that that may be the issue so thank you for sharing.
Networks seem so simple but are really much more of a black art the HA ever is. I’ve come to the conclusion, unless you really know what you’re doing, that it is often a matter of luck if everything works as it should out of the box.
