Domoticz

Moroen can you have a look at "Unable to iterate groups" error and the "Error in annouce: 160628"?

Sorry for the late reply, the latest commit should address this, but an ongoing problem is maintaining a stable connection, as soon as a request times out, the plugin/adapter goes haywire... Working on a solution, but I fear that until the switch to aiocoap is done, this will continue to be a problem...

@moroen,

I would recommend against the 'switch to aiocoap' because the Python Framework does not support asynchronous operations and libraries.

The framework is single threaded, does not enable Python threads in the interpreter, nor it does not use the Python Global Inter Lock. The code within Domoticz is thread safe only where it interacts with the Python garbage collector.

This is documented on the wiki page explicitly.

What problem are you trying to solve by using aiocoap?

Thanks for the input!

There is no async code in the plugin itself. In order to support COAP, the solution consists of two separate parts. The plugin (plugin.py) communicates with an "adapter" using telnet, so the plugin is single threaded and synchronous, without any external libraries. All the "heavy lifting" is done by onMessage and onCommand.

The adapter then uses COAP to talk to the IKEA-gateway, and send appropriate messages back to the plugin. I'm currently considering using aiocoap for the adapter, in order to mimmize the impact on the gateway when observing changes.

In time I would like to see the the plugin-system support COAPS as a communication protocol, but that's far beyond my expertice!

@moroen,

The framework is designed to allow protocols to be added pretty easily (they are polymorphic so you can just drop a new one in that supports the required interface) without risking existing functionality. I looked up COAP and it looks like it would work well.

There is already a C++ library that does all the hard work: https://github.com/staropram/cantcoap (clearly written by someone with a sense of humour ) which is handy.

I could look at it next week if you were prepared to test it out, I don't have any COAP devices.

That would be absolutely fantastic! I'm more than willing to test it out!

In order to use it with the IKEA-gateway, it needs to support secured COAP, COAPS. I took a quick glance at the library you linked to, and it appears not to support DTLS. There's a C-coap library that supports DTLS called libcoap: https://libcoap.net/, is this something you can use?

I just updated to the latest git commit, all seems fine now (with two groups). Thanks!

Also polling works (after turning a light on with a remote, this also shows up in domoticz). Is it also possible to monitor an input device (e.g. a motion sensor)?

Did you get your hands on the RGB bulb yet?

Still not available on the web-pages, but I'm going to a Ikea-warehouse in Oslo someday this week, so I'll take a look!

Found it on Ikea yesterday and bought a couple. Currently working on adding support. I have found a way to select the predefined colors, not sure if the bulb also supports full spectrum, but experimenting with pytradfri to find out!

Excellent news!
You have probably already found the various operations available in pytradri for setting RGB and stuff. Looking forward to see what you come up with

I'm struggling with making sense of the color-picker, the values returned to the plugin when selecting a color doesn't make sense to me. I would guess HSV, but the HUE-value is always -1? Using RBG it appears that the bulb is somewhat full spectrum, just need to get some kind of usable color-information out of the picker.

For now I can implement support for the "predefined" colors, as they are implemented in the official tradfri app from IKEA, but until I figure out the picker, full color support is out of my reach...

M

Just a small heads up: According to https://github.com/ggravlingen/pytradfri/issues/90, a new firmware version of the Ikea Gateway will render the current implementation of pytradfri, and thus this domoticz plugin unoperative until pytradfri is updated with support for a change in the way the gateway handles DTLS...

Regards,
M

The latest commit to the plugin on github supports the new IDENT/PSK credentials of the latest IKEA gateway firmware, and supports/requires pytradfri version 4.0.2 or greater.

Support for color-bulbs are on it's way, I hope to push a new commit with this feature in the next couple of days!

Regards,
M

Basic support for color-bulbs implemented. I'v been unable to make sense of the color-picker, so full RGB support is still lacking.

Thinking about implementing some kind of "custom" levels, where it would be possible to specify the desired colors using RGB rather than the predefined ones found in the IKEA Tradfri app.

Hello,
I have domoticz with tradfri plugin up and running, i set devices as groups, but I cannot use the buttons in domoticz, I want them to use them so I can do things with them through domoticz, will that be possible?

Switching groups on/off should be possible, could you specify some more? Any output in the logs when trying to switch a group?`

Hello,

UPDATE : just rechecked how i set up everything and i notice that it is said to Clone IKEA-tradfri plugin into domoticz plugins-directory ~/$ cd /opt/domoticz/plugins/
but my domoticz directory is /home/pi/domoticz. So I had to change every command starting with /opt/... by /pi/...
Guess this mustn't help...


I've set up this plugin following instructions but I'm stuck at this stage :
coap-client -m post -u "Client_identity" -k "GATEWAY-KEY" -e '{"9090":"IDENT"}' "coaps://IP:5684/15011/9063"

I must miss something really obvious but still, I need help :

GATEWAY-KEY = security code from the back of the gateway

IDENT = ??? I read in github "IDENT is the desired identifikation-name" ... so i've tried something like "Ikea"

Client identity = ???

So i've tried the following :
coap-client -m post -u "Client_identity" -k "xxxxxxxxx" -e '{"9090":"ikea"}' "coaps://192.168.1.95:9063" and just get v:1 t:CON c:POST i:6697 {} [ ] nothing more.
I've tried with the three port (5684, 15011 and 9063) same results except one difference :
coap-client -m post -u "Client_identity" -k "xxxxxxxxx" -e '{"9090":"ikea"}' "coaps://192.168.1.95:5684"
v:1 t:CON c:POST i:cb0e {} [ ]

So can you point me to the right direction
Thanks in advance for help

That coap-client line should work, I copied it from your post and substituted my own values, and it correctly returns a new PSK.

- Are you sure the gateway is running the latest firmware?
- What's the version of chap-client?
