Z-Wave stick + Danfoss RXZ2 channel; switch (Central Heating)

Hey Bruce , no worries and certainly no apology from anyone bar me, required.

No I didnt think it had useful Z-Wave info., I will scour the net for Endpoint/Class mappings - that should be a help. On it now


Not to worry. I think we have enough to get it working if needed.

@sihui or @chris I made a pdf from the scans and uploaded. I have no way of requesting review though. I think this is a non-plus device so I just made 1 group with no lifeline.


Cheers Bruce. Im not finding the information on Danfoss site, there is some scattered around the net like z-wave alliance etc but not at the level reported as errors to be fixed on your/the db. I have emailed Danfoss-EU and Danfoss-UK but they will need to channel that to their tech specialists so I’m not holding my breath too long :roll_eyes:

There is nothing in the manual about association groups or configuration parameters. We know the device supports association groups but any details.

I think the entry as it is not should work but the system, for some reason. does not let me ask for it to be reviewed. The others know how to resolve that.

Spent hours looking for Z-wave details on this product.
Nothing to the level of Association Groups although it can act as a controller and pair to a Danfoss RF tx/rx Thermonstat of which there are several. I looked at some of the datasheets for these but all they mention is having a single Node association.On the controller, Endpoint 0 is the controller side. 1 is Channel 1 and 2 is Channel 2. Not much help I also searched for Configuration Parameters that may extend function, but no joy.

Head hurts

Tomorrow I will open up the controller and see if I can determine the chipset and search on that spec. I dont believe Danfoss own proprietary RF Intellectual Rights at the chip level so that’s another line of enquiry - tomorrow.

Finally, I believe Danfoss took over or renamed, the Devolo brand. Mmmm.

Nite all / or morning depending what side of the pond you are…And for those at least 8hrs behind us here, god bless you and the US of A with all the shit going on around [Qasem Soleimani:. It’s all that has been on the news for the seven hours Ive been trying to solve this Danfoss thing. :slight_smile:

Unfortunately this won’t help - there is only 1 supplier of ZWave chipsets (Sigma - now taken over by Silabs), and as it is a microcontroller, the features are completely determined by software and defined the manufacturer (ie Danfoss in this case).

Ahhh ok Chris. What a Bummer !! :frowning: Well, I hope Danfoss Engineering Team in Bedford UK reply to my email. I sent it from my company address so hopefully it may attract attention, it may not.

Sleep for me now
Thanks Chris, Bruce, for all the super support. We will get this sorted - I’m not giving up.


hi again
no response from Danfoss at yet.

how can i help with the snapshot testing , if at all?

I just requested a review of this database item because it appears we cannot get more information.
Hopefully by the time the database gets exported and into a snapshot binding, we can have a good method to manually install a binding.
Currently the snapshot jar files appears to only be on the build server which is not guaranteed to be accessible. Normally they are also hosted on another server but I see the files there do not appear to be current.

Appreciate your reply, albeit rather, or to be more accurate, way above my head with respect to OH.

may you grace me with a laymen reworked reply?


  1. The new entry did not get added to the database export this weekend, partially because I hoped for more information and partially because I forgot to click a button asking for Review.
  2. After the entry is reviewed, Chris normally exports the database to a server about once a week.
  3. Once on the server, the openHAB process that builds test versions will produce a file that can be used for testing.
    4, Hopefully by that time we will have an easy method for you to try the binding.

ok, understood, much appreciated Bruce.

I’m aware you may presume that, as a software engineer myself, that i understand. However, it’s rather like myself, asking you the leam, to follow our software design and delivery process for class 1 NATO t secret military product… it takes years to become proficient in our respective fields :grin:

Actually , I am a Network Engineer at a pretty good sized University.

Maintaining complex systems such as network switches ans servers requires some amount of software work, especially when trying to hide some of the complex “magic” from end users.

I’m impressed Bruce. Network Engineers - well at our company - would not normally possess competencies at the Application , Presentation and Session OSI layers, but would be specialists at the Transport, Network, Data Link and Physical layers; but you’re doing the lot with OH it appears.

In regard to this thread, I’m waiting on a response from Danfoss in Bedford to provide the data requested for the db update. I have received a ticket notification from their support team, just waiting for their reply.,

Thanks. I was previously a Unix Sysyems Administrator for a team of a couple of hundred design engineers. One of my customer teams provided a design parts library 30 worldwide sites. Automation and scripting are useful tools. That is how Perl got started, for instance.

I live and learn :slight_smile:

Back to the OP…
I posted a question that might of helped me obtain latest Z-wave binding:

and was tipped off about the usability in that post. So how might I get hold of the updated Z-wave binding that , if and may, have been updated to include this device I need to get working?


You can get the latest binding here -:


Unfortunately at the moment it has not been updated since the weekend and I think this device was only published this morning - the next planned update will probably be Friday night.

Oh Chris that’s great, thank you for the link. I’ll give it a go next Monday then, just in case it sneaks in :slight_smile:
Still not heard from Danfoss , rather bizarrely however, I emailed their UK Engineering and got a reply from HQ in USA. Mmmm. As always I guess patience is a virtue.
Cheers again Chris.

It should be in in the next update - if I get a chance to do a quick update tonight I will, but I’ve got to head north for a few days tomorrow and can’t easily do an update while I’m on the road.
