Adding Parameters to Aeotec Nano Dimmer

I recently updated the firmware on my Aeotec Nano Dimmers (reference documentation).

According to the changelog, they’ve added parameters 40-45 to the nano dimmer, to allow it to to control the (optional) attached Wallswipe. I’m assuming this would require updates to the binding, in order to support this? I don’t see any option for parameters 40-45 in the UI or in the device database. There’s nothing in the thing XML file for the dimmer relating to the new parameters, either. What would it take to get these parameters supported?

Also, is it possible to manipulate thing parameters in rules or scripts? I was planning on changing the color of the switch LED based on different scene activations and alerts, but I’ve never had to dynamically change a parameter before.

So, they (Aeotec) added some features. For them to be available in OH we would need to add them to the device database listing.
Since this is firmware-specific, we need to make a new entry based off the old one but with a firmware requirement.
You never mentioned what version of OpenHAB you rare using. The zwave binding can be updated separately to get the new features, after the database has been updated. The process to update varies depending on the OH version.

I’m using the 2.4.0 release (Docker image).

Are you planning on upgrading your dimmer?
Looking at some of the changes (association changes), we will likely want the xml file from the new firmware device.
@chris can give us proper direction.

I’ve already upgraded the firmware on the dimmer. If it would help, I can upload the file this evening.

I think it may help due to the new association options.

Here is the xml file generated by the binding, but it doesn’t contain any information relating to the new parameters.
network_c3f37c26__node_5.xml (24.8 KB)

OK, I have started on the database item. What version is the new firmware? 2.04?
The old was 2.03 according to the document.

@kendaop I have been able to make an entry for the new firmware but we cannot find the information needed to add the new configuration parameters.
The upgrade document just lists their ID numbers & description. We have no information on the values for the different options (& their description) or the size of the configuration parameters. If needed, we can usually guess size from the minimum & maximum option values.
The user & engineering documents we could find online have not been updated for the new firmware. If you are able to find us the information, we can add it to our database.

I found some more config information, but still incomplete, from another open source project. I am working to get that added to our new entry.

A little rough, but just submitted the entry for review.

  1. Reviewed
  2. Published to Githib
  3. Snapshot Jar built
  4. Upgrade the binding. I recommend the install script.
    Zigbee and Z-Wave manual install script

Sorry for the delay. It appears that the firmware version is 2.03. That’s the version number indicated by Aeotec’s upgrade executable, and the version reported by the Zwave PC Controller app. But you’re right, they seem to indicate on their upgrade page that they just updated FROM 2.03. I’m wondering if I don’t actually have the latest version of the firmware.

According to

you have firmware version 1.2

Do they need to delete & re-add the Thing to rebuild the xml after a firmware upgrade so they cam export it for us?

Deleting and readding the Thing does not rebuild the xml file.
Reinitialization rebuilds the xml file.

Sorry, no idea. As openHAB does not support upgrading firmware versions (it is on the to-do list, though, but will take a while) I have no experience what to do after a firmware upgrade :sunglasses:

When does “reinitialization” happen? Are you referring to reinitialization of the binding, OH2, or the zwave device?

I’m running OH2 in a Docker container with my config stuff mounted into it, so it would be a piece of cake for me to create a new container, which would essentially provide me with a fresh install of OH2, if that’s what it takes.

Either when the XML file for the device is not found (eg if you delete it), or if you click on the Reinitialise option in the configuration.

The XML I refer to is in the {userdata}/zwave folder.

Ok, I reinitialized the device, and here is the new xml file.

I tried running that upgrade script, but it broke my zwave binding installation. I managed to re-install the stable version of the binding through PaperUI, but I’d like to attempt manually updating it. I couldn’t find any thorough instructions on how to do that, though.

I’ve grabbed the snapshot of the jar file and placed it in my addons directory, but I can’t figure out how to actually install it. Any ideas?

I ran that script on 2.5M1 successfully and multiple people used it with 2.4.
If you uninstall the binding, I think OH will automatically load any addons in the folder. I believe the newer zwave binding needs another one too, though.
The new entry will not be available until the new binding has been released anyway.
The xml now shows application version 2.3 so I will update the database with that.

Updated my item with your xml.

  1. Item gets reviewed
  2. Binding gets pushed to Github
  3. jar is made as part of OH snapshot.

The updated binding will then be available with the newest item but not before all the previous steps.
