No Lights in Home App

[n30ngruu3n]

Hello,

i've configured the tradfri-plugin and updated the config.json, homebrigde starts and reports:

Now i fixed this error with upgrading node to the latest stable version and recompiling all plugins & home bridge. Now its a timeout error during startup:

The buffer that's printed as debug looks wrong: <Buffer 2f 75 73 72 2f 6c 6f 63 61 6c 2f 6c 69 62 2f 6e 6f 64 65 5f 6d 6f 64 75 6c 65 73 2f 68 6f 6d 65 62 72 69 64 67 65 2d 74 72 61 64 66 72 69 2f 64 69 73 ... > means /usr/local/lib/node_modules/homebridge-tradfri/dis ...

So I'm going to guess that this is actually telling you that either

1. your binary cannot be run (missing permissions, wrong platform maybe)
2. or your binary could not be found

Try this and post the result: /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux -u 'Client_identity' -k 'EcOVQv3DooRatowg' -B 5 coaps://192.168.178.25:5684/15001

[n30ngruu3n]

I guess you're right!

Output of the command is: -bash: /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux: cannot execute binary file: Exec format error

Any idea to fix this?

[n30ngruu3n]

with sudo'ing the output is: /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux: 1: /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux: Syntax error: ")" unexpected

I hope this helps..

[0ff]

Hm, this is where it gets a bit tricky. Try uname -a and post what linux you're on. Might be it's just unsupported by the build of this tool.

[0ff]

Wait. You compiled the coap-client-linux yourself, didn't you? Also post the output of the command file /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux then

[n30ngruu3n]

Linux LimeGreen-Pi 4.9.24-v7+ #993 SMP Wed Apr 26 18:01:23 BST 2017 armv7l GNU/Linux

• it's a RaspberryPi 2 with Jessie Lite running on it

[n30ngruu3n]

I've compiled it myself!

Output is /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=257d0d6afad7ed139c38ca1c8b7782393ba4d77a, not stripped

[n30ngruu3n]

Just an idea, is the "x86-64" argument the problem? While running on Arm-v7?

[0ff]

Okay let me guess: You've compiled the tool on your desktop, then moved it to the raspi? 😄

Unfortunately, that won't work. You'd either need to cross-compile it (that's the way down the rabbit hole, but it's the right way) or you need to find a binary built for ARM - such as the one attached.

NOTE: DO NOT TRUST A FILE A STRANGER SENT YOU OVER THE INTERNET For all you know, this file will go ahead and fry all your stuff. Or install malware. Or whatever. Maybe, just maybe, this is coap-client exactly as you need it (/usr/local/bin/coap-client: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32, BuildID[sha1]=33514c635aa9de307a71f88bc965b2f87c021c4f, not stripped) but yeah, probably not.

coap-client.zip

[0ff]

Or just run these instructions on your raspi and save all of the cross-compiling trouble 👍

[n30ngruu3n]

Oh well, I didn't compile the package on my mbp, but it's possible, that I followed a guide for macOS and just copied the commands to the shell without givin' a thought about the compile instructions.. (maybe I mustn't play around with such things when I'm tired... :D ). I'll give the compile instructions a try ✌🏽 A big thanks until this point!

[n30ngruu3n]

I've copied the coap-client from /usr/local/bin/coap-client to /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux and now the output is, as expected, ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32, BuildID[sha1]=77f6888bcd438059b7fdc08f0668ef0737fcfe1c, not stripped but the timeout error persists...

but at this point there isn't a line about the buffer, so I think we've got a step further..

[n30ngruu3n]

By the way, i've tripple-checked the psk and the ip address, it's both correct..

[0ff]

Yes that sure looks better. Try running /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux -u 'Client_identity' -k 'EcOVQv3DooRatowg' -B 5 coaps://192.168.178.25:5684/15001 yourself and see if it responds with a list of devices. Haha, I was literally just typing this: "Check your IP and PSK" but then your 2nd response came in. Okay, so run it and post the results.

[n30ngruu3n]

Sadly there are quite no devices...

pi@LimeGreen-Pi:~/.homebridge $ /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux -u 'Client_identity' -k 'EcOVQv3DooRatowg' -B 5 coaps://192.168.178.25:5684/15001
v:1 t:CON c:GET i:c822 {} [ ]

🤣 , yeah I thought it was the right moment to get this point clear..

[0ff]

This weird, if you are sure that the IP and PSK are correct then there must be something wrong with the gateway. See, this is what should happen:

$ coap-client -u 'Client_identity' -k PSK -B 5 coaps://gw:5684/15001
v:1 t:CON c:GET i:3bb9 {} [ ]
decrypt_verify(): found 24 bytes cleartext

Instead, your client runs into a timeout (my guess is that the shell only returns after ~5 secs, correct?). To debug this, tell the client to print debug info like this: /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux -u 'Client_identity' -k 'EcOVQv3DooRatowg' -B 5 -v 9 coaps://192.168.178.25:5684/15001

Oh also please try ping 192.168.178.25 and see if the gateway is setup correctly :)

[n30ngruu3n]

Well, that's the output with the additional debug information:

$ /usr/local/lib/node_modules/homebridge-tradfri/bin/coap-client-linux -u 'Client_identity' -k 'EcOVQv3DooRatowg' -B 5 -v 9 coaps://192.168.178.25:5684/15001

may this be an encryption problem? 🤔

[0ff]

Hm, sorry, this is where I'm out. It looks like they start talking to each other and then fail to communicate. Why that is, though, I have no idea. Even if I change my PSK to an invalid value it looks very different from your log, it seems to me that the Raspi is not receiving a response from the gateway. Are there any kind of firewall rules in your network shielding the Raspi from access?

Sorry, but as I said I can't help you any further :( Maybe try the same command on your linux host, if it works here then there's a network problem. The client you've built earlier will work on your host.

[n30ngruu3n]

Thanks for your commitment. I think I've found the problem at side of the gateway.. Done a Portscan with macOS Networkutility on a port range of 5000 - 6000 and there aren't any responding ports.. But now the problem is how to get the gateway responding..

[n30ngruu3n]

Additional information: even if I skip the user and key params the output remains the same. So I think the needle hole is at the gateway-part

• I'll give Wireshark a try and sniff the traffic from my iPhone (Tradfri-App - which is quite working) to the gateway..

[0ff]

Yes, do that :) Also please verify the gateways firmware version inside the app, mine is at 1.1.0015 and just maybe this has something to do with it.

[n30ngruu3n]

I think I've found the problem.. Tradfri Gateway Version is 1.0.0008 . But how to update the Gateway? If I click "check for updates" it doesn't do anything..

Wireshark output seems clear from any packets by or to *.25 .. even if I change options in the Tradfri App. I am quite confused..

[n30ngruu3n]

Starting from scratch was the solution! Complete reset of the gateway and now it has updated to 1.1.0015 and the lightbulbs are recognised in the home app.......

A very very big thanks to you for your commitment! happy
