Arduino Sensors for Loxone

Use an Arduino to present various sensor readings on a legacy Dallas 1-Wire bus. Primarily designed to interface with Loxone, but could work with other systems too.

Currently provided:

• MQ135 presented as single DS18B20.
• SHT31 temperature & humidity with 1 minute deltas presented as single DS2438.

Note: OneWireHub DS2438 emulation with Loxone was fixed with PR #97. Until that is merged, use this alternate branch of the OneWireHub library:
