I am trying to find a solution to control my new Nilan Combi 302 Polar ventilation system. I have just purchased Homey Pro 2023, and hope to find someway to integrate the Nilan (which also has AC function). My Nilan has the Gateway LAN module built in. I have taked to a guy who has made a ESP modbus module for it, but he only supports Home Assistant, as it has an open source interface. Is there anyway that this talented guy can get access to programming it up against Homey Pro ? Scenario/Scene example that would be desired: Window switch is activated → Nilan should go from Cooling Air to Bypass Air Let me hear - I am eager to get it sorted. ---

This might work also with your device > **[GitHub - jascdk/Nilan\_Homeassistant: Use your Home Assistant to control and read...](https://github.com/jascdk/Nilan_Homeassistant/tree/master)** > > master Basicly with D1 mini you make the Nilan2MQTT device. Get the mqtt broker running on Homey or elsewhere and get the info to Homey. ---

Hi. Any updates on this matter? I’ve just published an app for my device. I have a Nilan Compact P - Air9. I’ve been struggling with different versions and documentation and very pleased with the result so far. Maybe I can provide some input. > [@\[APP\]\[Pro\] Nilan Air](https://community.homey.app/t/app-pro-nilan-air/100504): > > Hi all. I’ve just submitted an app with Homey support for Nilan Air. I’m the owner of a Nilan Compact P - Air9 heat-pump. With LAN-connected and network settings configured, I am now able with this app to get data from the device into Homey. Communication is local-network based and using ModBus communication. The journey getting data from the Nilan Compact P has been very challenging (and time-consuming) and this topic we can share information/troubleshooting. The CTS-7000 controller is inst… ---
