What is it?

The Open AIR Valve is an open-source, Home Assistant-compatible valve designed for Ducobox Silent ventilation systems. It allows you to control airflow within your ventilation system, directing it to specific rooms as needed. This helps optimize energy use and improve your home's comfort.

If you want to place the valve directly into a 125mm air duct choose the external housing option!

In Action:

Why did you make it?

During showers, my ventilation system would pull warm air from the living room, triggering the thermostat to reheat the room unnecessarily. This wasted energy and increased environmental impact. The Open AIR Valve solves this problem by allowing me to shut off the living room vent and redirect airflow where it's needed. Its compatibility with Home Assistant means I can fully automate this behaviour to suit my lifestyle.

Important Notes

Alignment for Installation:
The valve housing features two notches that must align with the Ducobox's housing for proper installation.
Disc Positioning:
Do not manually rotate the valve disc! Install the disc as received; its position is preset to automatically home after installation.
Foam Requirements:
A Ducobox ventilation system has seven inlets. To determine foam requirements:
7 - Number of Valves = Foam Blocks Needed
Example: If you install two valves, you’ll need five foam blocks.
Sensor Limitations:
The valve supports one sensor in the same ventilation hole.
If you need both RH and CO2 measurements, a combination sensor is required.
Original sensors are not supported due to housing incompatibility.
External Valve Housing:
For mounting the valve outside the ventilation box, you’ll need:
125mm flexible tube: Buy Here
Hose clamps for 135mm diameter: Buy Here
12V adapter with 5.5x2.1mm jack: Requires 12V, >200mA.
Mounting hardware (screws, bolts, wall plugs).

New Design Highlights

Redesigned PSU with:
Improved LEDs.
Individual filters and fuses for each valve.
Installation images may differ slightly due to the redesign, but the steps and component locations remain unchanged. Updated visuals will be provided soon!

Special Thanks

Great product! If you have a Duco ventilation box - buy it.

Currently the Duco box is equipped with two valves and the mini. Absolutely love it. It’s so easy to manage through Home Assistant and integrate with for example light switches in toilets. And yes - that connection can be life saving 😬😁

Perfect

Using product in my current Duco ventilation box. Easy setup, well documented. I chose for pre programmed and it shipped quicker than expected. Works like a charm!

Open AIR mini & Open AIR Valve

A few weeks after the delivery and installation its time to give a review. The Open AIR mini & Open AIR Valves delivered pretty fast, good packaging and no troubles at all with the installation. Only follow the guide on Github and had everything pre installed. Now running for a few weeks with Home Assistant automations with no problems at all.

Flamingo lets the people know that the original Duco sensors/remotes are not supported. As a side note, its possible to power up the Duco print and only use the Duco network to use the original Duco sensors/remotes.

All in all I cannot think of any thing negative....

Keep up the great work!

Excellent valves

Received the valves today and was able to install in less than 45 minutes. The most time was needed to place the sensors on the valves. Took a while to figure out we had to remove the housing. The notches on the valve for the sensors are a bit low which made it difficult to keep the sensor in the right position. Once the sensors were installed, the whole system is plug-and-play.
As with the Open Air Mini, the password for the access point is “ChangeMe123!” (which took some googling to find). In the end, after figuring this out, everything installed easy. Connecting to the wifi is simple and Home Assistant discovers the valves instantly.
Only thing I needed to do was to deactivate the sensor-entities that were made by the Open Air Mini and I had my automations running in under 5 minutes.

Perfect!

Perfect example that opensource works better than the original product. It is well designed and manufactured

Amazing way to gain home assistant control of your ducobox

Really happy to install this and gain control of my ducobox, an exceptionally well built product with clear instruction to swap out the controls.

Kleppen met sensoren en Open air systeem voor duco silent

Goede kwaliteit van de materialen, snel geleverd en makkelijk te integreren in Home Assistant. Automatiseringen worden door alle mogelijkheden wel wat complex. Maar dat is juist wat iedereen wil. Communicatie met verkoper is ook super.

Super blij met de producten :)
