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

[dzjr]

Glad it worked out for you!

I've been toying with an idea to handle the whole IDENT/PSK-thing differently, I'll use your experience as motivation to finally getting it implemented...

Regards,
M

Excuse me for the late reaction, nice to hear the you used my experience as a motivation!

Preheps it is also posible (for @GGravelingen ) to look at the libcoap install script, i had some problems whit installing it.

Removing the dependency on libcoap is the next big thing on the list, I just need to decide whether to keep using python for the adapter or switch it to something that supports COAPS a bit more natively.

Thanks!


Got it working indeed , missed an update of Domoticz, but as this is handled as a package, had to pick a beta from Jadahl.
Great!
All I now have to figure out is to have the "python3 tradfri.tac" as a daemon / service on Synology.
Not as easy as it sounds..

Great stuff this plugin!!

Could I as you a question, as I do not have access to a synolgy? How easy (or difficult) would it be to compile and run a golang application on a synology nas? I am currently experimenting with other implementations of the plugin.

The latest version of the plugin's development branch now has a rather major change, a change that will break a current installation of the plugin, though rather easy to fix.

Instead of generating a (or using a known) IDENT/PSK pair, and then entering this information on the plugin setup page, the IDENT/PSK is handled by the adaptor, and generated using a configure.py python scipt, which need to be executed once before the adapter starts.

Anyone updating to the newest version are encouraged to the check out the readme for instructions, and report errors, problems or suggestions in this thread. Hopefully this change will alleviate a rather common problem getting the adapter to run, as you only need to supply the gateway IP and master-key on setup, no more manually using the coap-client directly to generate the IDENT/PSK-pair.

M

Hello Moroen (and others here)

Thank you for the new version, i had some problems whit the plugin so i try-ed a new install and i used the new tutorial (off course).

It works very fine!
The only problem i have is whit installing the COAP client from GGravelingen (it is not working) and the error that i don't have the service_identity ( pip3 install service_identity helped.

and now it is running without problems.

Thanks again!

I am not familiar with golang, sorry about that.
It was just a flow of getting and installing make, automake, gcc, python3, pip3, twisted and so forth.
I do have a second Nas available where I can try to get it to the current state , unfortunately it is not really working anymore (had it working for a moment).

My version is as following:
IKEA-tradfri COAP-adaptor version 0.7
Development Branche
Domoticz 4.9992 via Jadahl.com

Running the adapter via

Code: Select all

sudo /volume1/@entware-ng/opt/bin/python3 /usr/local/domoticz/var/plugins/IKEA-Tradfri/tradfri.tac

Domoticz connects, but it is stuck at the following:

The errors were my fault, somehow the IP got changed for the gateway, after which I received really weird results that the python script received return calls.

if someone else get these:

Just check the IP address of the gateway you are trying to reach from Domoticz..

Ikea has now the new Control Outlet plugs in store, and I have them here.

But the are not yet working with this plugin, the work in the Ikea app.

I guess the device code/name must be added to devices.ini.....

Or are you planning an update for support of the Control Outlet?

Unfortunately, the tradfri outlets are still not available here in Norway, and until I get my hands on a couple of these things, I don't think I'll be able to implement support for them in the plugin. If someone could post the model description I might be able to get it working without having a real outlet, but I wouldn't be to hopeful.

I'll keep my eyes on the IKEA-website, and I plan to order a couple of these outlets as soon as they are available and implement support for them!

@moroen: many thanks for the plugin. Took a bit of reading thru the entire thread to figure out which combination of components I needed but works great now.

Couple remaining questions:

• any thoughts on adding the controllers as devices in domoticz? motion sensors and so on? Would be great to use tradfri actuators in domoticz for other purposes...

• what is a workable polling frequency? Especially if the actuators are also available as deives, any thoughts on the possibility of a notification (from the coap adapter) rather than a polling approach?

Again, great work and cannot wait to see the wall plugs included.

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 )

Adding controllers would be a high priority, but as far as I know, it's not currently possible to monitor these devices using the coap-api, but I haven't checked this in a while...

As far as a workable polling interval, I would generally recommend as long an interval as possible, as to frequent polling seems to crash the gateway from time to time. Getting proper observation has proven to be a major stumbling block, as I've been unable to implement this in any kind of reliable way. Either the gateway stops sending notifications after a variable number of observations or after a variable amount of time. I've even tried to implement the adapter in other languages (where the one using golang is the most complete) to get reliable observations, but to no avail. I'm not giving up, but it's currently not a high priority.

I'm very interested in you experience in getting the plugin to work. I've been toying with various version of the plugin for so long now, that I'm probably completely blind to the different steps needed in getting it to work. I try to install it "on a clean system" (actually a debian docker-image) when something in the setup changes, but I'm probably making way to many assumptions along the way. So if you would be as kind as to point out what you found difficult, I could try to make the readme/instructions a bit clearer, or if you feel so inclined, update the readme and issue a pull request!

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...

M

Hi Moroen,

My key challenge was the fact that I don't follow all the betas (too dependent on domoticz to let a beta mess things up) but an somewhere in the end 4.99xx. Having messed with python myself, I recognized the json.decode issue in onCommand but never realised I needed to be on your beta channel. Then I didn't think/read and continued with the hub IP rather than the adapter IP... But that was resolved quite quickly once I kicked my brain in gear (in my defence, I can say that I had just woken up from a < 6hr sleep after my birthday celebration with the mates still suffering big time from alcohol abuse).

Mostly (all) my bad essentially.

[moroen]

Thanks to rwijbenga, who very kindly donated a couple of outlets/sockets to me, the latest development version now supports controlling the IKEA Tradfri outlets/sockets. Adding the sockets to the IKEA gateway using the official IKEA app and then restarting domoticz after pulling the latest development branch should add the sockets to the existing IKEA-devices.

If any trouble getting the plugin to work after the update, please note the changes to how the plugin handles the IDENT/PSK-pair, as described in the readme.

As always, reports of errors, suggestions etc are most welcome!

Regards,
M

Did you update coap? There were some changes to support the plugs in coap.
Pip install --upgrade

[moroen]

Support for sockets require the latest version of pytradfri - 6.0.1

Btw, since the new version I get a LOT of errors on the plugin having ended unexpectedly. It runs but still.
