I haven’t found anything about Danfoss Link underfloor heating system compatibility. The system consists of main controller ( Danfoss HC5 or Danfoss HC10) and 014G0158 thermostats. It is also supposedly z-wave. Does anybody know what kind of information can be read/set via z-wave? I’ve read that Danfoss does not always expose useful features via z-wave.
I am researching underfloor heating for our new home and have come across the following smart systems with wireless thermostats and controllers:
- Honeywell Total Comfort Connect and Evohome products
- Danfoss Link and Danfoss Icon products
- Uponor Smatrix Plus with U@Home and Uponor products
It seems like most of the products can be mated to any of the controllers as they all control 24V solenoid actuators.
At this stage HA only has an integration for Evohome, while there is a custom integration for Uponor U@Home.
The Danfoss API requires an expensive license fee. See https://github.com/JonasPed/danfosslink2mqtt
If there are any other options for Australia (which is more european for this type of installation) let me know.
Revisiting this topic. I am using Danfoss Link CC at the moment, it is zwave system, using their own central unit.
Since it is zwave, I was thinking of removing central unit and replacing it with Home Assistant.
At the moment I am using their room thermostats, 2x HC10 to control acutators for underfloor heating, and I have one “spare” boiler relay.
Since I am not using Boiler Relay, I tried pairing it to Danfoss, and it worked fine, recognized by ZwaveJS and can control it as it is simple binary switch.
I did not have any luck with room thermostat, it is paired fine but not recognized at all. I suspect Danfoss might be using something custom, as for instance if you change temperature on central unit/phone, set temperature is immediately displayed on thermostat (in regular zwave operation, it would be relying on wakeup interval, right?)
Since it is winter and I can’t afford experimenting with unpairing HC10, pairing it to HA to see if it works or not, and then adding it back to danfoss, I am curious if someone is using or tried to use HC10 on Home Assistant (ZwaveJS). It is essentially only 10x relay for acutators + 2 relays (boiler, pump) and few additional inputs.
Thanks to everyone.

I just started with Home Assistant yesterday, but I really would like to get my Danfos under floor heating in HA, the Danfoss-app is horrible…
Sad to say, no. I have not had time to look in to it.
Has anyone had any luck with getting danfoss link to work?
I wanted to integrate my Danfoss Link system with Home Assistant, and after some trial and error, I successfully added the devices using the following steps:
- Set up Amazon Alexa to work with your Danfoss Link system.
- Install Homebridge on a server or computer (I’m using a Raspberry Pi 4).
- Add the Homebridge Alexa Smart Home plugin to Homebridge.
- Follow the setup instructions for the Homebridge Alexa Smart Home plugin. (I opted to install it as a Child Bridge.)
- Once your devices are successfully integrated into Homebridge, add a new HomeKit device in Home Assistant using the HomeKit pairing code displayed in Homebridge.
- Your Danfoss Link devices should now be available in Home Assistant.
While this method is a bit convoluted, it appears to be the only viable solution at the moment for integrating Danfoss Link with Home Assistant.
Note: As of now, I can only view the current temperature of each device; setting the target temperature isn’t working yet. I’m also encountering frequent errors in Homebridge for the devices: InvalidResponse(State not available).
This is my first time using Homebridge, so it’s possible that I’ve missed some settings. If anyone has suggestions or tips, I’d appreciate the help!
