OpenZwave group associations

fastie81 · September 12, 2020, 8:02am

Hi, I have been using OpenZwave beta integration for a few months now, and then one thing I cant work out is how to set a node association.
Does the current beta support associations or is this to come?
If it does, is there any documentation I can be pointed at?

Any help is much appreciated

Thanks

It does.

Sure thing.

MQTT Client for OpenZWave
=========================

Docker Repo: https://hub.docker.com/r/openzwave/ozwdaemon

Make sure you have create a local folder where ozwdaemon can store the config files etc for your installation. In this example, /home/ozw/config/ is on your local machine. 

If you are using Secure Communications, setup a Docker Secret:
```
printf "0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x0A,0x0b,0x0c,0x0d,0x0e,0x0f,0x10" | docker secret create OZW_Network_Key -
```
* replace the Hex String with 16 Bytes to use as your Network Key.

Start a container with the following command line:
```
docker run -it --security-opt seccomp=unconfined --device=/dev/ttyUSB0 -v /home/ozw/config:/opt/ozw/config -e MQTT_SERVER="10.100.200.102" -e USB_PATH=/dev/ttyUSB0 --secret OZW_Network_Key openzwave/ozwdaemon:latest
```

* Update `MQTT_SERVER` with the IP address of the MQTT Server and all `/dev/ttyUSB0` entries with the path to your USB Stick.
* If you are not running with a ZWave Network Key, remove the `--secret OZW_Network_Key` command

Thanks for the info
Sorry for the noob question,
Would I send this association via homeassistant or MQTT explore?

fastie81 · September 13, 2020, 8:27am

I think I got it worked out… Thanks you so much

Freddan101 · September 13, 2020, 5:25pm

I have the same question. May I ask how you solved this?

fastie81 · September 13, 2020, 8:18pm

Hi @Freddan101

After a bit of digging this is what I did to get it working.
I used MQTT Explore
publish an event to topic “OpenZWave/1/command/addassociation/”

{
“node”:67,
“group”: 3,
“target”: “73”
}

Params:
“node” - uint8: The NodeID to test
“group” - uint8: The Association Group you wish to add a member to
“target” - string: The Target Node you wish to send notifications to for this group.

most of the info I got from this.

in my case, my node had 3 devices. so I had to look at the group related to my switch(Switch2) which was group 3. you can see all this in MQTTExplorer under associations.

Hope this helps. Let me know if something is not clear

Many thanks @fastie81. Seems I got it to work.

Brian_Schou · November 21, 2020, 7:36pm

i’m trying to do this for one of my devices but i cant get it to work, could you guide me on the right way

bernhard · November 21, 2020, 7:38pm

Same. Trying to associate two devices, MQTT response is ok, but if I check the association afterwards it’s not there and also does not work.

firstof9 · November 21, 2020, 10:48pm

You’re doing it wrong. You’ve messed up the topics as well, restart your ozwdaemon.

Brian_Schou · November 22, 2020, 5:24am

@firstof9 that was exactly what I was afraid of. Is it possible you could try to explain what I have done wrong and how I do it right, I would like to learn this, so understanding what I have done wrong and learning what I shall do to get it right would help me.

firstof9 · November 22, 2020, 5:31am

It’s properly outlined in the previous post.

Topic: OpenZWave/1/command/addassociation/ <— Note the trailing / SUPER important.
Example payload:

{
"node":67,
"group": 3,
"target": "73"
}

Brian_Schou · November 22, 2020, 9:18am

Hmm okay if i understand it correct, it should look like this

{
“node”:27,
“group”: 2,
“target”: “27.2”
}

Brian_Schou · November 22, 2020, 9:56am

I Get this error

firstof9 · November 22, 2020, 3:42pm

Incorrect, you are using the ‘fancy’ quotes, look at my example again.

Brian_Schou · November 22, 2020, 4:14pm

Okay That was embarrassing. i will try again

firstof9 · November 22, 2020, 4:19pm

That looks correct to me.

Brian_Schou · November 22, 2020, 6:26pm

I have done it with all the 14 endpoints and did a restart my HA and the OpenZWave Beta, but i cant get a return signal, it just keeps switching back, du eny of you have a idea to where i have to look for that problem?

freshcoast · November 23, 2020, 12:34am

Maybe you could explain what you are trying to do? It looks like you’ve associated a node to itself, which is a bizarre thing to do.

Brian_Schou · November 23, 2020, 2:41pm

@freshcoast
Okay i got a multichannel device with 10 outputs and 4 inputs, in the manual says i have to associate the outputs with the main device
