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

[AxelvanH]

Hi Moroen,

I just deleted the Plugins/IKEA-Tradfri directory and started over with the instructions.
One thing that comes to my attention is that this command does not work.

cd domoticz/plugins/

Instead i have to manually switch to: /usr/local/domoticz/var/plugins/

Could that have something to do with some issues?

Kr,
Axel

Just to answer my own question, it does not
The only 'handicap' is that you need to move to this location yourself.

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

Hi Moroen,

I deleted the whole TIKEA-Tradfri directory and started over again from scratch reading every line meticulously...
Keeping a log off all the messages in the progress. Now everything (except from chaning to the plugins directory differently) worked fine!
Connection is established and all devices are reported.

My appologies for taking your time, I hope the below will help other users.
Thank you for the great work, answers and patience!

Kr, Axel

On the question, where things went wrong, I guess in the switching between installs.
https://github.com/moroen/IKEA-Tradfri- ... /README.md

Point 1 is easy.
Point 2 can be skipped as explained.

At point 3, I go mistaken by the first paragraph. At the link towards coapcmd, I emidattely clicked that.
But the steps for synology should be:

1. Get Golang envirionment:
Download right version xxx
tar -C /usr/local -xzf go1.15.2.linux-xxxx.tar.gz
export PATH=$PATH:/usr/local/go/bin
go version

2. Goto pugins-dir
cd /volume1/@appstore/domoticz/var/plugins

3. Get Coapcmd
plugins/IKEA-Tradfri# git clone https://github.com/moroen/coapcmd.git
plugins/IKEA-Tradfri# cd coapcmd

4. Execute install
plugins/IKEA-Tradfri# bash install_coapcmd.sh

5. Select coapcmd
/plugins/IKEA-Tradfri# python3 plugin.py api coapcmd

6. Configure coapcmd
plugins/IKEA-Tradfri# python3 plugin.py config 192.168.2.71 Key12345678

step 6 only works with the proper IP address of the gateway, else it will fail with:
{'Result': '', 'Status': 'HandshakeError'}
Connection timed out

7. python3 plugin.py list
Listing all connections.

8. Restarting Domoticz and adding the plugin.

There is a new version of the plugin available, 0.10.0. Unfortunately this update brings a couple of breaking changes, and I urge everyone planing to update to check out the updated readme.

Tradfricoap (the API for controlling the gateway) has been separated out into it's own module, available on pypi (https://pypi.org/project/tradfricoap/). On well configured systems where the interactive interpreter is the same as the one used by domoticz, the upgrade should be simple:

Code: Select all

$ cd plugins/IKEA-Tradfri
$ git checkout master
$ git pull
$ rm -rf tradfricoap
$ sudo -H pip3 install tradfricoap

On systems where domoticz is unable to find or use system modules, tradfricoap can still be installed into the plugin directory with git:

Code: Select all

$ cd plugins/IKEA-Tradfri
$ git clone https://github.com/moroen/tradfricoap.git

For systems using coapcmd, there is a new version of this as well:

Code: Select all

$ cd plugins/IEKA-Tradfri
$ sh ./install_coapcmd.sh

or download the latest prebuild binaries.

To check installed versions:

Code: Select all

$ python3 plugin.py version

The syntax for configuring the gateway connection and selecting an api for coaps has changes slightly:

Code: Select all

$ python3 plugin.py config gw IP KEY
$ python3 plugin.py config api py3coap # for py3coap
$ python3 plugin.py config api coapcmd # for py3coap

For updating the plugin:

Code: Select all

$ cd plugins/IKEA-Tradfri
$ git pull
$ sudo -H python3 -m pip install -U tradfricoap py3coap

If tradfricoap has been installed into the plugin dirctory, update with git:

Code: Select all

$ cd plugins/IKEA-Tradfri/tradfricoap
$ git pull

M

First I want to thank you for all your great work Moroen!
I followed your steps, but after a restart of Domoticz it still shows version 0.9.17.

Any thought?

With kind regards,
Andrès

There was an error in my instructions, you need to checkout and pull the master branch. The original post has been corrected:

Code: Select all

$ cd plugins/IKEA-Tradfri
$ git checkout master
$ git pull
$ rm -rf tradfricoap
$ sudo -H pip3 install tradfricoap

Sorry!

Regards,
M

[dressie]

Yes! That seems to work! Thanks!

when entering checkout master this is the right reply right?

Code: Select all

Already on 'master'
Your branch is up to date with 'origin/master'.

and later on I get this

Hi Moroen,

I thought about updating my windows machine, so i downloaded the latest 32bit wheel (py3coap-0.8.0-cp37-cp37m-win32.whl) and installed it.
pip list shows: py3coap 0.8.0

Is it correct there is no 32bit version of the py3coap 0.9.0 ?
Do i need to go to a 64bit python? I dont think Domoticz works with a 64bit Python... not sure to...

I then updated the plugin to 0.10.0 and tried:
python plugin.py list
The response is: py3coap not found

Is this because i need py3coap 0.9.0? Did i mis something?

The win32 version of py3coap is missing in the latest build on pypi, I'll look into it!

I just installed Python 3.7.9 64bit on a Domoticz test virtual machine.
Installed the plugin version 0.10.0
Installed py3coap 0.9.0
Installed tradfricoap 0.0.11

And....
python plugin.py list
Lights:
65537: lamp keuken (State: 0 - Level: 71 - Hex: None)
65538: keuken verlichting (State: 0 - Level: 0 - Hex: None)
65540: buitenverlichting voor (State: 0 - Level: 2 - Hex: None)
65541: Woonkamer (State: 0 - Level: 2 - Hex: efd275)
65544: aanbouw 1 (State: 1 - Level: 91 - Hex: None)
65545: aanbouw 2 (State: 1 - Level: 5 - Hex: None)

Domoticz says: PluginSystem: Failed dynamic library load, install the latest libpython3.x library that is available for your platform.
This is because of the 64bit version of Python ofcourse.

Thanks in advance

If you compile domoticz yourself, it's possible to support 64 bits python, but it's probably not worth the hassle...

py3coap version 0.9.1 just released on pypi. This version is the same as 0.9.0, but with wheels for win32 included, support for python3.5 has been removed.

Regards,
M

[JimmyH1969]

Mhhh.... i installed py3coap version 0.9.1

Pip list:
py3coap 0.9.1

Copied the plugin to the Domoticz plugin folder.

Executed: python.exe plugin.py list
Result: py3coap not found

On my 64bit python machine the same configuration works without problems. Did i miss something?

[JimmyH1969]

Removed py3coap-0.9.1 and installed py3coap-0.8.0
Removed plugin 0.10.0 and installed plugin 0.9.1

Everything works again, but there is a pause between switching 2 lights, that's why i wanted to update

I'll see if I can dig out a copy of Windows and do some testing. If it's any consolation, the 0.9.1 version doesn't solve the delay between switching lights, that's due to a workaround for a recent firmware update...

M

[JimmyH1969]

Oke, to solve my problems for now i went back to the stone age ....

Removed py3coap completely
Installed pycoap-0.7.0-cp37-cp37m-win32
Installed Plugin 0.7.3

I think thats the last possibe combination of pycoap and the plugin

Everything works fine. No delays in switching lights.
I think i missed the why and when going from pycoap to py3coap...

Anyway, for now it works!

Hm, that's interresting, what is the firmware version of your IKEA gateway?

[JimmyH1969]

Hi,

The IKEA App says it's on the latest version... not sure ofcourse
The HUB says: version 1.11.51

Is that the latest?

[Jasper79]

FYI 1.11.51 also latest version number on my set up.

Don't know if someone already looked at the question I posted earlier?
