Hello Chris,
Thanks for your work! I installed an R-208 today and installed your Homey-app. It seems to be working fine. It would be nice if the RH-sensors in my thermostats would be readable in the app (so I could boost my ventilation when RV goes up). Could that be done?
Update:
I did some tweaking in your app Chris, and now I can see the hunidity from my thermostats and use it in flows. I’m not a programmer at all, so I may have made some stupid errors, but for me it works!
this whould be great, how did you add it?
Hi Michael. I tweeked Chris’s code by adding a capability for measuring humidity. Then I uploaded the tweeked code directly to my Homey via the command prompt (and set the app not to update…)
Hi,
for my new home i would like to automate everything and my installer/contracter is installing the Uponor Smatrix Wave. I’m a little unsure whether I need the Uponor Smatrix Pulse Interface R-208, as it would cost me an extra €500. I was hoping I could connect without it.
Does anyone know if the extra interface is required or not?
Kind Regards,
Marcel
Hi Marcel,
I think the easiest option is to use the R-208 to connect the Uponor-unit to the cloud and then to Homey. Maybe there is a way to communicate directly using RS485 (there are examples on Home Assistant) but then you have to bring in your own expertise on coding. My smatrix unit was installed without an R-208 and I added it later myself, paying euro 125,- for a new unit on a Dutch marketplace. Placing the unit is just plug and play (in my case there was already a piece of din-rail available to click it in). For me that was the easy option.
Best regards, René
Hi René,
since i’m a software engineer, maybe the coding option is a nice challence to start with 
Once everything is in place i will give it a try and if low budget options fails i will buy the R-208.
Thanks,
Marcel
Hi,
ik probeer de upunor te koppelen maar ik kan alleen maar de thermostaat in de woonkamer vinden. Niet de thermostaten op de eerste verdieping in diverse ruimtes. Iemand een oplossing?
Hi all,
I have published a new test version of the app that includes the following functionality:
Additionally I have done some stability improvements that should help with reported network issues.
Please install the test version via Uponor Smatrix | Homey and give feedback!
Hi,
Please post your question in English since this is an international forum.
To debug your issue, can you post a dump from the app’s debug data (available in the app settings)? Then we can check if there’s an issue with the configuration of your Uponor installation or if it’s an issue with the app. So you see all the thermostats in the app from Uponor?
thanks for replying. I can see the thermostats in the upunor application. Where can i find the debug information?
Hi @Vitace , I mean the Homey Uponor app setting there is a debug info field in there.
Hey @ChrisTerBeke , can it be that the last update from yesterday (1.0.3) broke the automatic update from the thermostates to the homey app? Devices seem to be online, Net scan can reach the device but the current temp only gets updated after restarting the app, while the Uponor app on my phone gives the correct temps.
Hi,
Could be, but I’m not experiencing issues myself and have been running this version as a test for almost a month now. Maybe a re-connect of the devices will help?
Chris
Notice for existing and new users:
Uponor has started rolling out firmware that requires an mTLS connection between the client and the Uponor Smatrix control unit. Unfortunately they have implemented this in such a way that no static client certificate and private key are shipped in the Uponor iOS or Android apps, so I cannot reverse engineer this mTLS connection in Homey. Instead they are using a library called Approov which dynamically generates certificates and are likely installed on the Smatrix control unit during initial setup of the mobile app.
This means that I cannot add support for newer firmware versions, until Uponor makes their local API available for 3rd parties as well. Unfortunately they have indicated in communications with another Homey Uponor user that they have no plans to support 3rd party clients.
So for now: if you have a working Homey Uponor connection, DO NOT UPDATE THE UPONOR SMATRIX FIRMWARE. This will likely break the Homey Uponor app. If you have a new unit that comes pre-installed with a recent firmware versions, you cannot use the Homey Uponor app for now.
I will contact Uponor about this situation, since not having proper smart home support in 2026 is a no-go and will result in people buy other underfloor heating systems. Hopefully more information soon.
