Hallo zusammen
Ich habe das Beispiel Parking (https://www.mysensors.org/build/parking) getestet und mit einer Antenne zum Gateway gesendet.
Code Arduino:
/**
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

*
* REVISION HISTORY
* Version 1.0 - Created by Henrik Ekblad
*
* DESCRIPTION
* Parking sensor using a neopixel led ring and distance sensor (HC-SR04).
* Configure the digital pins used for distance sensor and neopixels below.
* NOTE! Remeber to feed leds and distance sensor serparatly from your Arduino.
* It will probably not survive feeding more than a couple of LEDs. You
* can also adjust intesity below to reduce the power requirements.
*
* Sends parking status to the controller as a DOOR sensor if SEND_STATUS_TO_CONTROLLER
* is defined below. You can also use this _standalone_ without any radio by
* removing the SEND_STATUS_TO_CONTROLLER define.

Im FHEM wird der Parksensor erkannt, jedoch sind die Readings meiner Meinung nach vom Fensteröffner.

Wie kann ich den Status Car parked / Car gone in FHEM anzeigen?
Wird dieser Sketch von FHEM schon unterstützt?
Gruss Zurli
Schaue es mir morgen an. Gruß
Du hast Recht im Sketch werden die Variablen des Fensteröffners verwendet:
Zitat* Sends parking status to the controller as a DOOR sensor if SEND_STATUS_TO_CONTROLLER
* is defined below. You can also use this _standalone_ without any radio by
* removing the SEND_STATUS_TO_CONTROLLER define.
Er sendet also nur einen Status "geparkt" oder "nicht geparkt" an FHEM.
