Nibe uplink binding

Tags: #<Tag:0x00007f173aef1e58> #<Tag:0x00007f173aef1cf0>

Hello everybody!

First of all, I am aware of the current Nibe binding, which uses a physical connection, but I was wondering if if would be possible to use the existing Nibe uplink API instead? Of course this would need a new binding. As I’m planning on building a house with a Nibe heatpump and will be using OpenHAB I’d be really interested in this. I’d give it a shot myself, but my programming skills are nonexistent. There’s some discussion on using the API here, if anyone is interested:

Some time ago I wrote a script to read the values from Nibe Uplink (German):

I use the http binding to get several values into items. If you are interested, I could post my item definitions here.

Hi all!
This is very interesting.
My intentions is to switch my in these days very old woodboiler to an Nibe heatpump.
I have read and there are a lot of good information there.
I’m not a professional programmer but I do like to do my very best to have these things working. So my plan is to try to build a binding that will use the Nibe API as described.
I my case so will this switch of heating not take part before next summer, so this is still a very young project for me and I have still not yet an Account at Nibe, just done some small investigations regarding to implement OAuth2 in the so far not existing binding.
But I do like to contribute to make a binding which will do the work for us. I use Eclipse and will try to build build the binding in Java as described in

paphko, Please, post your item definitions.


For sure it would be interesting to see. I’m not fluent enough in German or code to read that other forum thoroughly but the part I did understand looks good. As far as I’m concerned getting the data in is enough. The heat pump could then be adjusted via IFTTT.


Excerpt from JSON response:

                "mittlere Außentemp.":"19.5°C",
                "Brauchwasser oben":"53.0°C",

http binding config:


These are three example items:

String nibe_aussentemperatur { http="<[nibe:900000:JSONPATH($.Status.Außentemperatur)]" }
String nibe_ventilation_drehzahl { http="<[nibe:900000:JSONPATH($.ventilation.Ventilatordrehzahl)]" }
String nibe_brauchwasser { http="<[nibe:900000:JSONPATH($.Status.Brauchwasser oben)]" }

That looks very interesting. I wish I could further develop it, but my coding skills simply aren’t good enough. Maybe Örjan could work based on this?


Now I think I understand what’s going on. So you host the the php somewhere, say your own RPi. That php connects to Nibe Uplink and parses the page for the values and creates json which is then fed into OpenHAB.
The credentials fed to nibe.php are forwarded to Uplink?
Actually, come to think of it, I think this does everything I need it to do. The control can be done via IFTTT.
Thank you very much for posting this, I think it’s excellent!


Just to clear some things out, is this right?

Thank’s , I will have a lot of help aswell of your examples, in my further investigations and development of a hopefully working binding.


I have created a Python script that checks Nibe Uplink every minute and pushes these values to MQTT. I can publish the code on the github if you want. After a small cleanup.

My script uses Nibe’s Private API. I just reverse engineered their web API. Works fine for 3 weeks already.

Great, I like to see your code, and no hurry, Please, take all time you need.
I assume that you meen the API’s that you have to authenticate by using OAuth2, and that’s seem to be a little bit tricky.
The link I’m thinking of is like:


No, Undocumented API. =)

Does that mean that you are in fact communicating directly with the machine instead of the cloud service?


No. The heatpump itself does not have any usable open ports. I’ve scanned it.
It has only 23/tcp open tcpwrapped
No idea what it is. It closes the connection as soon as I try to connect.
My script uses nibe uplink. But does the same that a user would do. Logs in with your username and password and then queries endpoint with a list of variables.

I see, very interesting.


I agree, what confuses me is that there seems to be different links and even different ways to catch up the parameters.
Regarding to is the interesting parameters catched up one by one. And you must before you even can catch them, make your account authorized and in this process get an token which you then use for further catching of parameters.
In your code, you will login in once and then catch all parameters as you described, right?
Is the result delivered as JSON?
Lot of questions is’nt it:slight_smile:

Locking forward to see your code.


And here is the promised code.

See examples/ to make it work as a service (This will authenticate ~ once a day).
All parameters are fetched in one request.

If somebody wants a debian package for the nibe -> mqtt bridge feel free to ask. That will simplify installation for non python people.

Great, I will have a closer look asap, but so far it’s look nice.



I’m the author of and I’m also an OpenHab 2 user though so far I haven’t attempted to integrate NIBE Uplink with OpenHab in any way. Like @yozik04 I’m publishing the parameter values I read from NIBE Uplink using MQTT so that’s how I thought I might get them into OpenHab in the future.

While MQTT should work OK for reading parameter values (e.g. to display the outside temperature in the OpenHab GUI), in order to use the Heat Pump “Manage” facilities (available via the Premium subscription for NIBE Uplink) I suspect we’d want to use some sort of tighter integration than MQTT.

Once you know the list of numeric Parameter IDs you want to retrieve (up to a limit of 15) you can do that via one API call with the Public API using GET{systemId}/parameters (at least according to the API manual - I haven’t actually tried that yet).

The challenge is knowing which set of numeric Parameter IDs apply to a particular Heat Pump installation - they vary by Heat Pump Model and by the presence or absence of optional Heat Pump Accessories in a specific Installation. That’s my excuse for having my script query the “Categories” for a particular Heat Pump “System” (i.e. a particular installation) and then grab the Parameters for each Category (via one API call per Category, and from memory there are 2 Categories for my installation) - plus I wanted to capture all of the available Parameters, and there are more than 15.

Thanks to @Basse_03 for mentioning he was working on this topic when he contacted me via my Blog, which brought me here…


Hi there,

I managed to create an Openhab2 binding for Nibe Uplink. It is written in plain java so it is fully integrated into Openhab.
It is still in an early state of development so it supports only read access currently and only a few parameters.

Reverse engeneering of those undocumented parameters is quite a lot of work and unfortunately it depends on the heat pump model. Currently the binding supports only one generic thing which has one channel for each parameter Id.
Maybe it would be better to have one thing for each specific heatpump model and one thing for each additional module (compressor, exhaust/supply fan module, etc). But that would be a lot of effort.

Please check out the binding here:


Great work, i will have a closer look asap, but first some questions.
You will make the nibeId once, when you are connected to the link described and then use this nibeId for all further collecting of posts, right?
Is it possible to set up an account without any working heatpump?

Regards Örjan
