My Issue

If asked alexa to discover local devices, then it is unable to find any device.

WHYT

• I started fauxmo running in debug mode to see the communication or any kind of error, however unable to find any issue. I also used the config of my friend, who is running fauxmo sucessfully, but also no success.
• control using IOS Alexa App or Echo - same issues
• running fauxmo as a service or from command line
• logging into my profile, or resetting the echo device to be registered to my profile is consistently successful in connecting to and controlling fauxmo devices.

Please see attached debug output, I can see the communication of my SONOS speakers.
If I asked alexa to discover a new devices, I could not see any request from network.

Echo device using the same network as my raspberry pi.

Thanks for the complete issue report!

Can you elaborate on this:

logging into my profile, or resetting the echo device to be registered to my profile is consistently successful in connecting to and controlling fauxmo devices.

So are you trying to get it to work without being logged into an account? Please go into more detail about the circumstances under which you are getting it to work, and how that's difference from what you're hoping to achieve.

Also, it looks like the log was only running for 5 seconds -- I presume you are running it for longer but truncated because there is nothing else to see?

Any firewall running on the device running Fauxmo?

[kovi44]

Hi,

logging into my profile, or resetting the echo device to be registered to my profile is consistently successful in connecting to and controlling fauxmo devices.
Statement above: This was an mistake - I just copy another report and forget to remove, sorry.

The 5sec. dump is just to not sharing long data, basically all the time the same messages from my sonos devices.
I run it for several hours and tried to discover a new devices several times using IOS app and echo dot show, but the issue is that I do not see any communication coming from echo.

I added my firewall rules

iptables -vL

so seems that I do not block any UDP data flow

both devices are using the same WIFI (UNIFI), no host isolation or any additional security settings. Strange is that I can see the Sonos speakers, which are on WIFI as well. I can see the SONOS communication on fauxmo in debug mode and my Echo Dot Show is able to find SONOS speakers too

[n8henrie]

Odd.

I'm far from a firewall expert, but the first thing I would try is temporarily disabling your firewall to see if that changes anything.

Also, I assume you've triple checked the static IP address you're using?

[kovi44]

Honestly, I already tried everything. Nothing really helps, I got no clue what else to verify.

1. there si no network limitation like firewall, one can see in debug log of fauxmo that broadcast message to 239.255.255.250:1900 are coming succesfully , my SONOS speakers can be visible in the log. If I understand correctly then as soon as I request alexa to discover local devoces a brodcast message should be visible in the log (no such a msg at all)

2. no wifi host isolation is configured on the wifi (my sonos speakers are connected to the same wifi as my echo dot show)

3. i tried sample config for fauxmo and several other, which works for my friends

4. I tried to do factory reset of my Alexa Echo show

5. My alexa echo show is able to find another devices on the network like doorbell or Sonos speaker

What else i should check to make it run?

[n8henrie]

Huh, this is an odd one.

there si no network limitation like firewall

This conflicts with your earlier statement:

I added my firewall rules

Yes, I think you're likely right that it's not the firewall. But my comment was this was the first thing that I would try; it is certainly possible to have firewall rules that restrict traffic coming to or from a specific host, so the fact that your sonos can broadcast doesn't necessarily rule this out, though it does make it less likely.

My next guess would be that it could be related to the Echo Show. I don't have one of these to test with, and I'm not sure whether I've had others use Fauxmo with a Show. Fauxmo has failed to work with some Alexa devices in the past, such as the wand as well as the webapp. Do you have another Echo device to test with?

Can you ping the Echo from your Raspberry Pi? If so, have you looked through the example tcpdump commands to see if there are any broadcasts coming from the Echo when you discover devices?

If not, there's not a whole lot that can be done on my end.

If so, please post and perhaps Fauxmo can be reconfigured to recognize whatever it is doing differently.

EDIT: Please also update your initial post with the Echo firmware version.

[kovi44]

Let me share my analysis

I checked using tcpdump requests from Echo Dot Show. I can see the udp broadcast packets comming to my eth0 interface, which is also configured in fauxmo json config file. (tcpdump -n udp dst port 1900 -A)
If I tried command to emulate request from Echo (echo -e "M-SEARCH" | nc.traditional -q 1 -u 239.255.255.250 1900) then I can see it in debug mode of fauxmo

In debug mode in fauxmo I could not see any request from that device

I am able to ping the echo dot show from raspberry.

I will try to connect another echo device to see if there will be any difference and let you know

I also tested using fauxmo v0.4.9 0 same result

Hi all,

finally I found the issue!!! The issue was with routing table, if you have configured several interface (ifconfig), the be sure that your traffic is routed correctly!

to solve it please use command like "route add -net 239.0.0.0 netmask 255.0.0.0 eth0" where eth0 is interface using which the traffic should be routed

I would not have figured that out. Great work and thanks for sharing the solution!
