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 👇

I recently watched Jeff Gerling’s video on CO₂ levels, and how to monitor it. My home office is also in the basement, with no windows. So I paid attention to the air quality when setting up down here.

In addition to monitoring the CO₂ level, I’m also automatically ventilating the space when the air quality gets too bad.
