I assume that the Homey Homematic app and/or the CCU3 are not set up correctly.
The RedMatic and Mosquitto add-on software are not required, but the CCU-Jack add-on software is.
Thanks.
That seems to be a significant improvement.
Conclusion: the howto I did follow is maybe outdate.
On CCU:
I did delete RedMatic and Mosquitto.
I did install CCU-Jack.
I did configure Firewall and can reacht the CCU-Jack config page on the CCU.
In the CCU-Jack UI, I can see the devices, rooms.
On Homey:
I did restart the service.
Now it seems to have a successfull connection.
HOWEVER:
- Adding a device looks still the same, maybe the search take a bit longer.
- Sequenz is as to my prior screenshots: I can see the CCU, clicking âaddâ then leads to âno device foundâ.
Any more needed configuration on either end?
Are you sure that your devices are supported by the Home Homematic app?
Could you please name them?
From what I can understand from your first post, the Homematic devices are already a bit older, correct?

Ok, good question.
I have quite a bunch tot test at hand. 
Newer and older.
I did test with diffent yesterday, supported, unsupported, assumed supported (based on other systems. - the -2 / updated types).
After the change to CCU-Jack I did by mistake only test newer ones.
That was the problem.
So homematic App works now. I will summarize what I did later.
Examples
works - clear:
HMIP-PS
HMIP-eTRV
does not work - clear:
HMIP-PS-2
HmIP-SWSD-2
Thanks for support.
PS: Firewall settings have ben accoring to the mentioned link.
The two devices that donât work are not listed as supported, thatâs the problem.
Another problem is that the Homey Homematic app hasnât actually been updated for five years, apart from the current test version released on October 9, 2025. So the chances of additional devices being added are rather slim.
Weâve asked Athom several times to provide better support, but so far, unfortunately, to no avail.
If you want to continue using the Homey Pro and your Homematic devices, one option would be to integrate the Homematic devices into Home Assistant and then import them into Homey using the Homey Home Assistant Community app.
The Homematic HA integration (Link) is regularly updated, itâs all local and supports significantly more devices than the Homey Homematic app.
Like said, clear for the reason they are not working.
I actually don´t want to work with any self-managed (open source) component for my daily relevant components, for now. That is, why I came to Homey instead straight to home assistant.
I probably can live for a wihle to have some automation isolated on the CCU. I will look into IFTTT as a bridge at some point. However, my expectation ist, that Athom takes care. Imaging them - commercial product - pointing to Home Assistant as a bridge, which cann - open source - replace their product.
I did read about the discussions and their reactions here in the forum.
Due to my former job, I had a bit of insights into Magenta Smart Home and we did touch discussion about eQ3 partnering at some point. I can clearly say, that Athoms partner managers expectation here does not touch eQ3 (then) reality. That is not how there partnering works (our cloud partnerships did).
Decission is simpel:
- give up rock solid products as part of SmartHome and give up customer liking those, but a better software solution.
- or
- invest in the integration. Doing so, eQ3 gives a helping hand, nonetheless. Don´t exect them to, pay, they have no need.
So here is my conclusion what to do, to get a connection between Homematic and Homey up and running, as of April 2026:
You need a CCU2/3, or a Raspberr Clone - cloudy things like the access point are not supported.
My Journey start with brand new Homey Pro and a CCU3.
On the CCU: Install CCU-Jack
- Download latest stable release for CCU
- Look into the manual, Link on the Github page
- Add needed Firewall ports
On the Homey: Install Homematic App
In Configuration:
- Set Connection to CCU-Jack
- Restart and check log
Port here must be corosponding to CCU-Jack and CCU Firewall settings.
From here on, you should be able to add new SUPPORTED devices in homey.
Obviously, you must first add them to the CCU.
Only pain in the ⌠is, the ingreation has not been taken care of from Athoms side, for 5 years now. Think about security and alle the missing devices.
To be clear: most stuff you can buy today, while likely not work.
e.g. - a pluggable switch HmIP-PS ist supported, but end of production for years.
HmIP-PS-2 is by functionality and design the same, but small differences in communication make it incompatible.
Haven´t read anything about the optimal solution (Homey direct adding of eQ3 devices, without CCU et al).
Hi Ralf,
The links to the pages are on the right hand side, under âPagesâ: Home / CCU Jack Setup / MQTT Setup .
I agree itâs not very userfriendly, but itâs really there.
I have a problem where my thermostats arenât being recognized, but Iâm not entirely sure if theyâre compatible. I have the HmIP-eTRV-B-2 R4M. if some one can help me
that would be really nice
I donât use these thermostats myself, but according to the list of supported devices, only the HmlP-eTRV-B model is supported, not the HmlP-eTRV-B-2.

Is there a way to make them Supportet ?
As I learned a few days ago, the app hasn´t been maintained for years, just scroll up.
The company behind homey - Athom - seems to try Homematic to pay (partially?) for the integration. With eQ3 beeing a long term profitable SmartHome solution, they will not see the need. Their mother ELV is not to much into fast growth. I hab some insides in the debate via former coworker, that developed another Smarthome with eQ3 integregation.
So from my pov, Athom needs to decide wether the want to risk some pennys on the quite sollid given code, especially as in the next 6-12 month many users of another platform likely start dropping out of that. Meybee like you and me?
The CCU3 ist quite âouchâ from modern perspective, the new Cloud thingy limited.
The quality of the eq3 components is insane, if you look rather for something solid, than fancy. The only components I own, that have already a lifetime over 10 years.
So the CCU3 hub with the Homey App a cool solution.
If Athom would have eQ3 and support fort he upcomming Schellenberg hub (Matter, anyway), interesting market chance.
If you want to speak to someone, my understanding is, that
@Doekse
is in charge.
For the time beeing, personaly I wait and maybe configure a IFTTT/webhook work arround.
But only for 2 alarms. Not a good time invest for e.g. Thermostats.
Cheers,
Ralf
I can elaborate on this a bit.
At the moment, weâre not planning to maintain an officially supported integration for the Homematic CCU systems. There is an existing Homematic integration, currently managed by WebArray (one of our partner agencies), but it isnât actively maintained due to the rather rudimentary nature of the system.
We are working on an integration for the newer Homematic IP HCU, as that platform does offer APIs. However, collaboration with the Homematic team has been limited so far.
ELV actually reached out to us some time ago with the intention of selling Homey products through their webshop, and that listing has been ready on both ends for quite a while. The only requirement from our side is that Homematic products work properly with Homey.
At the moment, progress is being held back by a lack of responsiveness from the Homematic team regarding the integration. The latest update we received indicated that they currently donât have a way to verify partner integrations. This would require users to enable a developer mode on the HCU to use it with Homey, which isnât something we consider suitable for an official integration.
Itâs also worth noting that there are no costs involved for Homematic in this process. The integration is being handled by one of our development partners at our expense.
Iâd very much like to get EQ3 Homematic onboard as an official partner and welcome them into the Works with Homey program. But at the moment, it does feel like a bit of a one-way street.

Thanks, Abe, for giving us some insights. That matches my experience with Homematic as well. I guess weâll have to wait until they officially provide an option for verified plugins, which they already mentioned in one of their YouTube videos a while back.
Personally, I have already activated developer mode to make use of the existing Home Assistant plugin for the HCU, which has undergone significant development and has been performing great.
Wouldnât it be an option to keep the Homey app in beta status until Homematic provides an option for verified plugins, so Homey users at least have the choice?
The missing Homematic app for the Homey is the only reason I havenât switched to Homey completely, which I would really like to do. There are already a few plugins under development for the HCU, and pretty much all plugins available so far require developer mode. I guess those who want to use them accept that limitation (personally, Iâve never had a case where I needed support from Homematic so far).
That seems to be the current situation. In my opinion, a beta-status app would be better than nothing, especially in Germany, where many smart homes are built on a Homematic-based setup.
Home Assistant Plugin
System Health Plugin
Email Plugin
Feiertags Plugin
ReAct-Fluid-WebUI
Apple Home Plugin (under development)
By the way, Homematic has announced an official MQTT plugin for Q3/2026. Could that be a possible solution as well?

In that case you can already connect it using one of the available MQTT apps in the Homey App Store
Thatâs true, of course, but thatâs just an option for advanced users. And Homey is supposed to be a smart home platform for everyone, right? 
Fully agree, but the ball is in their court
It just feels like theyâre warming up very slowly over there 
Hopefully theyâve found the ball by now.
I have made a fork und scriptet my Thermostat in Now it works thanks for the help
