[REQUEST] Ikea Trådfri Gateway (smart lights hub controller) plugin?

[heggink]

No error messages, just domoticz complaining even though the plugin runs:

I suspect the plugin just takes more time to complete causing domoticz to complain... I have that on a number of other plugins as well but this one definitely outnumbers in terms of complaints . Just changed Domoticz.Heartbeat to 15 as that's mentioned to lead to these messages if above 30...

[heggink]

Domoticz.Heartbeat(15) did the trick. No more complaints.

[moroen]

Domoticz.Heartbeat(15) did the trick. No more complaints.

Thanks for letting me know, I'll change the heartbeat-frequency and update the branch!

Any idea what to do when getting this error?

root@domoticz:/home/system/domoticz/plugins/IKEA-Tradfri# /usr/local/bin/python3.6 ./configure.py 10.22.2.4 fnYhASmWfdfyFqa
Failed to generate ID/PSK-pair.
Check that the IP and Master Key is correct.

Is the format correct?

I tripple checked the key and ip. The key is also scaned from the QR code.

Have you tried:

Hi guys, I can't get the plugin updated. I want to use the beta of Domoticz because of a bug in Hue that is fixed in the beta. But after updating domoticz to beta the Tradfri plugin stops working. Updated that to the development branch version. But now the plugin won't connect to libcoap because it broke. It won't start. Anyone else having this problem (and a solution maybe )

Hi!

The latest developmen-version introduced a new way of handling the ident/key-pair needed for DTLS, so if you're upgrading from a previous development version or from master, you need to make a couple of changes:

First, configure the adapter:

Code: Select all

domoticz/plugins/IKEA-Tradfri$ sudo systemctrl stop domoticz
domoticz/plugins/IKEA-Tradfri$ sudo systemctrl stop ikea-tradfri
domoticz/plugins/IKEA-Tradfri$ ./configure.py IP GATEWAY-KEY
domoticz/plugins/IKEA-Tradfri$ sudo systemctrl start ikea-tradfri
domoticz/plugins/IKEA-Tradfri$ sudo systemctrl stop domoticz

And then you need to go to the hardware-page, select the IKEA-Tradfri plugin, and change the adapter IP-adress to point to where the adapter is running (localhost if running domoticz and the adapter on the same server).

This is documented in the readme-file of the development branch. If the instructions are unclear (which they probably are, since I'm generally rubbish at writing documentation), let me know what the sticking-points are, and I'll try to make them clearer...

Regards,
M

Thanks, Stupid me, , I didn't read the readme . Looks like its working now!

HI all,

I have the latest beta from domoticz on an rpi 3b.
I bought the ikea tradfri hub and a bulb. The bulb is working via the gateway and with the latests software and app.
Now i like to use my domoticz too. Is there documentation how to install trafdri gateway on my domoticz..

I tried:
https://rutger.kirkels.nl/2018/02/01/do ... s-tradfri/

But thats not working, i get an error that coap-client does not exist.
Is there a better manual that is working!

Thanks

[Stimpy68]

Is there a better manual that is working!

Thanks

This one: https://github.com/moroen/IKEA-Tradfri-plugin

But thats the same, are you using the stable or beta domoticz?

[pvklink]

mmm
It mentions that these requirements :

Requirements:
1. Domoticz compiled with support for Python-Plugins.
2 . Python library pytradfri by ggravlingen (https://github.com/ggravlingen/pytradfri). Required version: 6.0.1 or greater.
3. Twisted (https://twistedmatrix.com/trac/)
4. IKEA-Tradfri-plugin (https://github.com/moroen/IKEA-Tradfri-plugin)

i guess that i dont have to do step 1
but nr 2 and 3 dont have a clear install procedure...

I made a script install-coap-client.sh with
#!/bin/sh
git clone --depth 1 --recursive -b dtls https://github.com/home-assistant/libcoap.git
cd libcoap
./autogen.sh
./configure --disable-documentation --disable-shared --without-debug CFLAGS="-D COAP_DEBUG_FD=stderr"
make
make install

and started it with sudo ./install-coap-client.sh
and with this first command i get errors!

Heb je die pakketten ook geinstalleerd zoals aangegeven? Die heeft ie nodig om make te gebruiken als ik het mij goed herinner.
Did you install the packages as mentioned in the logs?

You need to install libcoap. Follow the instructions in the file called building.

Hi all!

Have been using the plugin for about a week now, after installing it according to the manual on Github and tips in this thread. Although it's running fine, I'm getting these errors when starting Domoticz:

Not a big thing I guess, because I can't find any reduction in functionality. The lamps react correctly and changes from the Tradfri app replicate within the time-out I setup in Domoticz:

Any ideas??

Interesting... Just to make sure that I have understood this correctly: Do the "Error: (Tradfri) 'onMessage' failed 'KeyError'" only occure when starting domoticz, or do you also see them during use? Do you have any of the new Ikea outlets added to the gateway?

So far it's only on initialization, when (re)starting Domoticz.

At the moment it's three LED lights with one motion sensor. Haven't bought the new outlets yet.

Sorry, answered to soon, did some testing shortly after the above reply. The error also logged when I change the state of one of the lamps via the Tradfri app:

The state of the lamp DOES update correctly in Domoticz. So the polling works.

Further research showed that the error occurred because I set 'Add groups as devices' to 'Yes' in the plugin configuration. After switching that off there's no error anymore. Does that make sense?

Sorry, answered to soon, did some testing shortly after the above reply. The error also logged when I change the state of one of the lamps via the Tradfri app:

The state of the lamp DOES update correctly in Domoticz. So the polling works.

Further research showed that the error occurred because I set 'Add groups as devices' to 'Yes' in the plugin configuration. After switching that off there's no error anymore. Does that make sense?

Could you please set debug to true, and post the log including lines before and after this error message?

Thank you!

I think I've found the bug, but I'm currently at work, so I'm not able to fix it right now... I'll fix this as soon as possible, and post here when a new version is commited to github!

Regards,
M
