We provide tutorial for the connection of the active Nilan recuperation unit, in our case the VP18 K WT type with OpenHAB 3. By communicating via Modbus it is possible to read the whole range of values, but mainly also to control the unit through OpenHAB. This allows us to remotely or programmatically change the performance and ventilation settings depending on the mode (night, cooking, etc.)

DALI device control via MQTTRating: 100%

DALI (Digital Addressable Lighting Interface) is an open interface for lighting controls in the home, industrial buildings, public objects, etc. To connect to our OpenHAB system, we can use a commercial converter from ADFWEB called HD67941-B2 - DALI / MQTT - Converter. In the article, we will show how to use this converter in conjunction with MQTT.
