Arduino Repeater messaging

Version 3.6 Alpha; Message format may (and will) probably change between LamPI releases

Introduction

When using the Arduino as a repeater for 433MHz messages, the board will pick up ANY well-known 433MHz communication and when a sensor is recognized will retransmit it over the air. There are a few specials which make the Arduino Repeater even more attractive:

Message Format

• REPEAT: The WT440 and other well-known messages are repeated without handling, Other receiver types are not yet integrated
• CONVERT: Auriol messages are handled differently, their protocol is "translated" to the well-known WT440 message format as described on the 433messaging page. (In fact we make the Auriol known as a WT440 device (no humidity).
• TRANSMIT: On-board repeater sensors of type Dallas (ds18b20), HTU21, BMP085/BMP180 will be transmitted over the air AS-IF it were WT440 devices. Airpressure of BMP085 will be coded so that the receiving Arduino Gateway can correctly work with its values.
• CONFIGURE: All sensors or receiver types can be enabled/disabled at compile time by editing the 433Repeater.h file.
