Titel: MySensors - Parking Sensor
Beitrag von: zurli am 24 Januar 2016, 15:49:53
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?

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.
