MYSENSORS Zählermodul für Gaszähler API 2.0

Gaszähler mit Impulsgeber

Hier schon einmal der Sketch. Mit ihm erzeuge ich die Zählimpulse in MYSENSORS. In FHEM verwende ich dann das Modul Gascalculator zur weiteren Berechnung. Als Kontakt verwende ich einen einfach Reedkontakt.

/**
 * 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.
