No Devices are dicoverd after a Echo Dot reset

[altheeagle]

Since yesterday I had a Problem with my Echo Dot v2, it stopped working (can't connect to my Wifi). After I resetted my Echo Dot and got it back running I tried to (re-)disover my devices and nothing has been found. The Configuration of my HA-Bridge Setup hasn't been changed (by me). I tried all steps in the troubleshooting section in the FAQ, but still can't find any of my Devices. In the Log (in the Webgui or in the journalctl) the is no trace of any connection attempts from my Echo Dot or any other Device habridge-log.txt

[bwssytems]

Trace upnp is not turned on for that log. Please turn that on, do a discover, then post the log.

[altheeagle]

Thank you for the fast Response. I've thought that I had "Trace UPNP Calls" set to true, but it was set to false. So I changed it to true on the "Bridge Control" Tab und hit Save, but it didn't save the Setting, it was set to false again. Did I something wrong?

[bwssytems]

Not sure about that not sticking. Do you see any errors in your log after you hit save that it cannot save to your config file? In your other log it shows that it is loading from a path in your home directory, is it writable by the user that is running the bradge?

[altheeagle]

I've manually added the value to the config file and now i get some more information in the log. If I read the Log correctly there is a request from 10.201.240.80 for a description.xml. This is my FireTV, my Echo Dot has the IP-Adresse 10.201.240.40, wich I can't spot in the log. habridge-log2.txt Edit: I've startet a Discovery by asking my Echo Dot also via https://alexa.amazon.de/spa/index.html#cards, And I tried the "Use Link Button"-Method as described in the FAQ.

I have the same problem. No device are discovered. I had to reset my Echo Dot too.

My guess is that Amazon is screwing around again. Same as they did when they blocked ports other than 80 last year. I added a new device and my harmony hub picked it up immediately, but the echo will not. Really wish Amazon would stop sucking.

[bwssytems]

@altheeagle Is this the correct network address for your ha-bridge: 10.201.240.6?

[altheeagle]

@bwssytems yes, thats rigth. Its the only IPv4 Adresse of the System, there are also couple of IPv6 Adresses assigned to the Networking Device.

[joshtaz]

I am having the same issue. Harmony will pick up/control my devices, but my Echos will not.

[cylon147]

facing the same problem with my 2 different setups

[DrUdoZucker]

Hi, as my setups have now stopped too - HABridge not longer detected by Echo - it worked fine for a very long time- I would like to know, when you will release an update (or where I can find your work in progress on this issue). Keep up your excellent work, which is highly appreciated.

[heikoh81]

Same problem here, has been working flawlessly for more than a year, now rediscovery is not working any more. Had 5.2.0, tried 5.3.0 and also 5.3.0a. Tried with UPNP delay 500ms, 650ms, 1000ms.

[glandecki]

Same problem. Suddenly stopped working and no success with different times nor igmp settings on switches/routers. Worked for a long time - now useless with Alexa

To be clear, it's Amazon that is useless. They are the ones that keep changing things needlessly.

[SelmaUrban]

What is your echo firmware version?

[Nachtfalke49]

I have 3:

Cube = 17951953028 Dot 2 = 651614420 Dot 3 = 3658075524

I tested it with all. Always pulled the power plug from the others. All don't work.

+1 What I don't get is how they don't break finding devices on phyiscal hue bridges out there. I don't suppose Hue is always changing their UPNP-Timings whatsoever...

[glandecki]

Maybe it is related that Philips announced that they cancel support to v1 bridge devices and they will not work with alexa. Is it possible to emulate higher version of bridge ? Refer to: https://www.imore.com/philips-hue-bridge-v1-support-ending-april-2020

[heikoh81]

I don't have any physical hue bridge. However, I always was under the impression that v1 bridge had local only support, while v2 needed a cloud connector? I think amazon will annoy many people if they drop local hue discovery. I think many tuya-plugs work that way, and tasmota also emulates hue or belkin-bridges.

[audiofreak9]

Is it possible to emulate higher version of bridge ? As @heikoh81 stated, v1 is local discovery, v2 is cloud, so not can't emulate cloud.

[SelmaUrban]

I found this about emulating a Hue bridge v2 with local discovery (see the Security section!): https://daenney.github.io/2019/04/09/emulating-philips-hue-bridge

The autor writes about the diyHue-Project. Here i found the file, which creates a self-signed cert: https://github.com/mariusmotea/diyHue/blob/master/BridgeEmulator/easy_install.sh that is used in: https://github.com/diyhue/diyHue/blob/master/BridgeEmulator/HueEmulator3.py

@bwssytems If v1 local discovery (http only) was droppt, is can be a option can you take a look at it and say your opinion on it

[Luigi8723]

Here same problem. After a update on the Echo (gen2) all devices gone. Had to reset the device and now i have some devices back. But i am still missing some. Running on 5.2.2. and not sure how to solve this.
Edit: tried again after reinstalling the alexa app on my phone "search for devices" an now it works again.

[bwssytems]

@SelmaUrban There is no need to use the HTTPS as that is an option and not a requirement.

[glandecki]

An update - I've played with Alexa and settings and reset several times the Alexa device. It looks like amazon problem (caching ?). I noticed that trying to run discovery not from Alexa itself (but from alexa app on iphone - add device, hue bridge v1) just after resetting device worked. Due to the lack of documentation for amazon echo discovery protocols and caching I can't say what happened to make it work, but essentially I've reset alexa and tried discovery from device and iphone app with bridge settings with and without "link" enabled in security settings (I've cleared all existing links beforehand). No luck for several tries. I've also ran tcpdump on my emulated controller interface. I don't get it but sometimes I could see alexa attempted to read from port 80 /description.... and sometimes not. After a while I've noticed that alexa discovered devices, but reported an error while trying to control them. Strange enough, habridge reported "security errors" "user not authorized" even when links were turned off. However after several tries and turning the linking off in security settings I've tried turning the emulated hue device (light) 'on/off' from the mobile app and "auto insert user" appeared in "manage links" and all works (so far), so definitely functionality is not (yet) removed from the newest Alexa devices (I have echo show 5).

For all: The new Release Candidate is out for testing.... https://github.com/bwssytems/ha-bridge/releases/tag/v5.3.1RC1

What I did to discover devices again:

• Remove all devices + Rooms in the Alexa-App
• Renumber all devices in the web interface
• Restart the raspberry pi
• Turn off alexa and wait a few seconds and turn it on again
• Search for devices

Tried this method as well, still no luck
