I really wonder how mqttmapper should handle the communication with an Itho ventilation communication unit.
In my opinion that is not possible. So, since you have already a JSON object available in Node-RED, the easiest way to communicate with
Domoticz is to convert the payload to the right format and send it by MQTT to Domoticz.
1. All data in the JSON object are numbers and not strings
2. you have a properly configured MQTT server, such as Mosquitto, running.
2. You have Domoticz configured to communicate with this MQTT server.
The 2 Inject nodes inject either 0 or 1 (1 equals "Open" and 0 equals "Closed"
1. Create a Dummy device in Domoticz Hardware
2. Create a virtual switch
3. Edit that switch and change it to "Contact"
4. Note its "idx" number.
5. Configure the MQTT out node, to the correct IP address and (if used) username/password.
You can simplle connect the "Function" node parallel to your "Debug" node.
Replace in the first line the idx number (105) with the one you noted in step 4.
