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

[Jasper79]

Last night the lights didn't turn on, This morning I tried them en getting this error.

Code: Select all

2020-09-01 08:27:51.330 Status: User: Admin initiated a switch command (61/Ikea Tradfri - Lamp Op Vitrine Kast/On)
2020-09-01 08:27:51.337 Error: (Ikea Tradfri) 'onCommand' failed 'KeyError'.

Nothing changed and the Ikea hub has a static IP.

[AxelvanH]

i'm struggeling to install the plugin onto my Synology 414 nas.
I believe I followed all steps correctly (after trying several times) but now i'm stuck at step 4, configuring the trafri coap.

The command sudo python3 plugin.py config 192.168.x.y ************** generates the following output.

Code: Select all

I have no clue how to troubleshoot this and can't find anything on this forum to push me in the right direction.

Hi Flexx/Moroen,

I have the same issue.
I was wondering where the command tries to write the config file as permissions issue seems related to that.
Flexx mentioned he chmod some directories??

Below my output. Similar config. Synology NAS and had to use coapcmd as the only viable option.

Just as a temp work around, Maybe it's also possible to manually create/edit the config file?

It might be possible, but then you need a working IDENT/KEY pair. I'm not an expert on synology, but from the error-messages, it appears that the plugin fails when trying to execute coapcmd, so that's before it tries to write to the config file. Are you able to run the coapcmd command manually?

[moroen]

The latest firmware update from IKEA appears to break the plugin when using py3coap as the COAP transport, as there is a significant delay between commands. It's possible to switch one device, and then there is a significant pause before it's possible to switch the device again, or switch another device.

Using coapcmd seems to avoid this issue, so as a temporary solution is to use coapcmd instead of py3coap:

Code: Select all

$ cd ../plugins/IKEA-Tradfri
$ sh ./install_coapcmd.sh
$ python3 plugin.py api coapcmd
$ python3 plugin.py list

This requires that git and go is installed.

Alternatively there are prebuild binaries available for linux-x86_64, arm v6 and v7, darwin (macos) and windows. Download the correct binary from https://github.com/moroen/coapcmd/releases and put the binary into the bin-directory in the IKEA-Tradfri directory and rename it to coapcmd (coapcmd.exe on windows). The bin directory might not exists, just create it before copying in the binary.

HI Moroen,

Thanks for the swift reply.
1. but then you need a working IDENT/KEY pair:
I have all the data, IP and key were left out intentionally
So if, IP and the identity key (bottom of hub) are enough I have those.

2. Are you able to run the coapcmd command manually?
You might be right that the OS can't find the command, should the directory be listed in the PATH?
Which command should I run to check that. just 'coapcmd' does not resonate at least

== Update, I added the dir of coapcmd to the path, that helped. coapcmd now works.
The error is still the same though.

You can't use the KEY printed on the bottom of the gateway in the config file. That key is the "master key", and it can only be used to create KEYS for new IDENTS. That'a what the plugin does when issuing the config command, it uses the master key to generate a PSK for a randomly created IDENT and then stores this random IDENT along with the generated PSK in the config file. So in order to manually specify a IDENT/PSK pair in the config file, you need to have a pair that's generated using a working installation...

In order for the plugin to find coapcmd, the coapcmd needs to be placed in a bin subdirectory in the IKEA-Tradfri directory.

Hi Moroen,

I have coapcmd working (updated my previous post) by adding the path to PATH.
So it now works from anywhere.
I tried the command agian, but the error message stays the same.
Is there anything else I can check?

Hi Moroen,

I kept on testing and discovered the following, that hopefully helps solving my issue.
When I delete the config.json file in the IKEA-Tradfri directory and run.
(IP and Code are fake, just for testing)

python3 plugin.py config 1.1.1.1 code
Py3coap module not found!
Install with "pip3 install py3coap" or select another api with "python3 plugin.py api"

So I run
python3 plugin.py api coapcmd

Which recreates the config.json file.

But running

python3 plugin.py config 1.1.1.1 code
Traceback (most recent call last):
File "plugin.py", line 177, in <module>

Again gives still the same error. chmod 777 on config.json did not make any difference.

My config.json file:

vi config.json

Any suggestion is welcome on how to proceed.

I'm still pretty sure that the error is a permission error when the plugin tries to run coapcmd, the error seems to occur at

Code: Select all

result = json.loads(subprocess.run([_coapCMD, "post", "--ident", "Client_identity", "--key", key, uri, payload],

Have you tried to set permission on coapcmd?

Code: Select all

chmod gou+rwx bin/coapcmd

The latest version of pycoap (0.9.0) and the plugin (0.9.5) now works with the latest IKEA Tradfri firmware 1.11.47. It's necessary to update both pycoap and the plugin to the latest version.

I'm not completely satisfied with this solution, it's a brute force solution to a problem I don't fully understand, but at least it's possible to switch more than one device without waiting > 45 seconds before switching another.

Unfortunately, it's noticeably slower when switching multiple devices than the previous version. When switching just one device, there shouldn't be much of a delay, but when switching several devices (as when using scenes), there will be a noticeable delay between lights changing state. On my system this delay is around 1-2 seconds between each light switching, so the lights turn on/off in an obvious sequence.

At the moment this can't be helped. I've not been able to figure out why the gateway just ignores PUT requests for around 45 seconds after receiving a PUT-request. It might be some kind of acknowledgement-issue, but since the API is not public, it's impossible to tell. The plugin and pycoap works around this issue by keeping the connection open between GET requests, but closes it after a PUT-request. The next GET or PUT request will then reopen the connection. Since updating several lights at once, entails several PUT requests, the connection gets closed and reopened several times, hence the delay.

M

[Jasper79]

Thanks I'll update.

I've used home assistant with trådfri before and that was instant all the time. It didn't need to wait for a pull from the IKEA hub.

Might want to have a look at that plug in to improve this one for Domoticz.

[Dutchhornet]

Works fine after the update of the plugin to 0.9.6.

[hairynoggin]

HI peeps,

can someone help me, I have updated the plugin to 0.9.6, but whenever I select it in the dropdown for "hardware" it always seems to revert back to 0.9.2 .... anything I can do to rectify this?

apologies if this is a repeat question

/

[MdeBoer]

HI!

I have the plugin updated tot 0.9.6 en PyCoap to 0.9.0 now I have the following error:

(Domoticz Version: Version: 2020.2 Build Hash: b63341bc0)

Can someone explain this?

Lights wil switch on, but it takes about 5 to 10 seconds to switch them on.

(Domoticz Version: Version: 2020.2 Build Hash: b63341bc0)

Can someone explain this?

Lights wil switch on, but it takes about 5 to 10 seconds to switch them on.

Please help!

PermissionError: [Errno 13] Permission denied

Again gives still the same error. chmod 777 on config.json did not make any difference.

My config.json file:

vi config.json
{"Gateway": null, "Identity": null, "Api": "Coapcmd", "Transition_time": 10, "Passkey": null, "Verbosity": 0}


Any suggestion is welcome on how to proceed.

Thanks,
Axel

I'm still pretty sure that the error is a permission error when the plugin tries to run coapcmd, the error seems to occur at

Code: Select all

result = json.loads(subprocess.run([_coapCMD, "post", "--ident", "Client_identity", "--key", key, uri, payload],

Have you tried to set permission on coapcmd?

Code: Select all

chmod gou+rwx bin/coapcmd

Reagards,

Hi Moroen,

Yes, I just did and run the command again with the same result.:
/volume1/@appstore/domoticz/var/plugins/IKEA-Tradfri# python3 plugin.py config 1.1.1.1 code
Traceback (most recent call last):

Let's try a different approach
How do I start with a 'clean install' ? Is it enough just to remove the Tradfri directory?

Thanks, Axel
