Are there any news regarding the motion sensors and the IKEA lightpanels in
the IKEA-Tradfri plugin? What is the current development state? I could not find
anything regarding this in the code base, did anyone already start working on
it?


Thanks

What is meant with IDENT in the command below, the desired identification name of what? The name of the Raspberry Pi on which I am installing the plugin, the name I would like to give to the TRÅDFRI Gateway or something else?
May the identification name contain spaces and letters such as Å for example?
And where will this identification name show up later? That may influence my choice for an identification name.

Code: Select all

coap-client -m post -u "Client_identity" -k "GATEWAY-KEY" -e '{"9090":"IDENT"}' "coaps://IP:5684/15011/9063"

Since communication is encrypted using DTLS, and IKEA has requested that the GATEWAY key is not stored anywhere, it's necessary to create a username/password (or IDENT/PSK) pair for communication. You could choose what ever you like, excluding special characters (like Å), spaces etc. It will later need to be entered along with the PSK on the plugin setup-page in Domoticz, and that's the only place it will be shown...

So test, ikea, ikea01, me, you, whatever is ok...

Thank you for your quick reply. You mention a username and password, but IDENT is only one value, right? Where do I enter the other value of the username and password?

/edit1
I understand now; the PSK is returned after sending the command.

/edit2
I am editing the ikea-tradfri.service-file. I have changed the environment path and user. I did a default installation on my Raspberry Pi, so the user is "pi". Is this group automatically created by Domoticz and can I leave it like this or...? I have installed Twisted using the command "pip3 install twisted", but then it is not installed to the path mentioned at "ExecStart". I assume that I need to change the path, but how can I find out where Twisted has been installed?

moroen wrote: ↑Thursday 08 February 2018 22:56 I haven't used a PI for a while, so I'm not quite sure about the default group for the pi user, but I would imagine it is 'pi'... You could test it:

Code: Select all

$ touch testing
$ ls -la testing

You'll get something like this as a response:

Code: Select all

-rw-r--r-- 1 mak mak 0 feb.   8 22:53 testing

The first is the user name, in you case pi, the second the default group

To find out where twistd is installed, you could use the which command:

Code: Select all

$ which twistd
/usr/local/bin/twistd

Hope it works out, if not, let me know, and I'll try to help further!

The which command does nothing unfortunately. Tried using twisted and twistd. No output whatsoever. Re-ran the command pip3 install twisted in the hope it would show a path, but it did not unfortunately. If you have any other ideas, that would be great. Not much of a Linux user here.

$ sudo pip3 install -U twisted

moroen wrote: ↑Friday 09 February 2018 13:31 You need to match the branch of the plugin to the version of domoticz you're using. It appears that your using the latest beta of domoticz? Then you need to use the developement branch of the plugin:

Code: Select all

$ cd IKEA-Tradfri
$ git checkout development

and restart domoticz... The devices shows up in the Devices tab in domoticz.

PS: I really should put some more work into the readme/instructions, but writing documentation is not one of my strengths...

When I run python3 tradfri.tac, I'm able to control the IKEA tradfri from the webinterface of Domoticz!!!

Thanks for your help.
I ran the commands you've provided, but still the service does not run as expected. I've rebooted the pi after I've ran your commands.
This is the output:

Thanks, I've ran your command, rebooted my pi without doing anything else (so not starting the service manually) and it now runs like a charm.

Thanks for your efforts and keep up the good work on this project! I read on the internet that IKEA will supply power supplys/power switches in the future, so this is a very nice project. Will keep following this.

Edit: sorry I'm completely a newbie in the Linux world...

Thanks!
