Controlling my Komfovent balanced ventilation system through Home Assistant — opens up a world of possibilities.
Here are three automations I use to make the system a bit smarter 🙂
Controlling my Komfovent balanced ventilation system through Home Assistant — opens up a world of possibilities.

We got balanced ventilation installed last year, and have been very happy with the system 🙂 But we quickly found that we needed to expand it into two more rooms — the 1st floor bathroom, used as the laundry room, and the play room, which will be a bedroom at some point.
Time to fix that 🙂
We recently got balanced ventilation installed, and I have interfaced it with Home Assistant. However — the ventilation unit have three “special modes” that can not be enabled through the Modbus interface; fireplace, kitchen, and override. These can only be set on the touch panel, mobile app, or through inputs terminals on the controller.
So I repurposed an old project and made a three-relay Wi-Fi controlled module, using MQTT to send commands and receive statuses.
Then used Home Assistant to automate it 🙂
We recently got balanced ventilation installed, and discovered that our ventilation unit has Modbus TCP/IP support. I even found a thread on the Home Assistant community talking about interfacing the C6 controller, which our unit has, into Home Assistant 😃
Here is my implementation 👇
Our house was first built as a log cabin in 1890, then extended in the 1950s, and again extended and completely renovated in 2000. It’s well insulated, and has no drafts — it seems to be relatively airtight.
Great for keeping the heat in, not so great for the air quality. Add the fact that we didn’t have a single fresh air vent, only those tiny trickle vents above the windows. What you are left with is a house with bad air quality.
So we installed a balanced ventilation system 🙂
