Nilan ventilation Quick App

[ChristianSogaard 71]

I want to stop Nilan when my extractor hood is Running, to ensure right airflow in the house - and a lot more great usecases.

 

For my Nilan Ventilation I have builded a small converter based on ESP8266 to convert the Modbus to HTTP or MQTT

Nilan Modbus firmware for D1 Mini (ESP8266) together with a TTL to RS485 Converter

Its two way communication with the Nilan

 

Getting values by HTTP:
You can get some json values from the Nilan by calling to it via HTTP. Just use your browser and type:

DEVICE - corresponds to the IP adress you you device (esp8266)

http://[device]/help - This should give you som registers

http://[device]/read/output - This would for example give you some status of the output

http://[device]/set/[group]/[adress]/[value]- This would make you able to send commands through HTTP

 

 

Getting values by MQTT:

Any MQTT-Tool :

ventilation/temp/#- This will give the temperatures from all the sensors.

ventilation/moist/#- This will give the humidity from the systems humidity sensor.

ventilation/# - This gives the output of the system - fan speed etc. Remember the payloads are given in values not text.

It based on a whole teams work in denmark, and everything its collected here.

There are

• 4 temperature sensors
• 1 Humidity Sensor
• 1 sensor for Fan Speed
• 1 sensor for Bypass (How much indoor and outdoor air is blended)
• 1 switch for user Program selection (can be On/Off) and select a Setting program in Nilan
• 1 sensor for Filter - indicating if Filter need to change.

 

Anyone else having Nilan or Genvex or already started on an Integration like this?

the way @jgab is working with QA Childs is just really amazing - I'm having a steep learning curve, and dont master the technique yet  

So looking for allies

If I have the Base QA and one working Sensor, I can manage to ADD the rest myself.

Hey everyone,

For those of you working with Nilan integrations and Fibaro QuickApps, here’s something that might make your winter projects a bit warmer 😊

Between November 11, 2025 and February 11, 2026, there’s a Winter Installer Promotion running at

, where every 4th license is completely free — no minimum order, no bundles, no commitments.

You just buy the license keys as your projects require them, and for every three paid ones, the next one is free.

It’s meant to support installers and integrators who handle heating and ventilation systems during the busiest (and often coldest) months of the year.

If you’re regularly working with Nilan

Stay warm and keep integrating!
