Previously configured by a fancy almost turing complete ini file, now simply hardcoded in dostuff_switch_lights.py running on realraum@mqtt.realraum.at.

realraum is littered with various sensors. As of 2015-11-21 they all communicate usinq MQTT, an Internet-of-Things Machine2Machine Messaging protocol using a central message broker running on mqtt.realraum.at (see ip-adressen) which in turn currently runs on a RaspberryPI2.

Our Code for controlling RF433 power outlets or switches or just controlling any cheap RF433 device via ATMega based µC.

Usually some daemon (1:new), (2:old), (3:client for 1 or 2) sends 3 byte rfcodes via serial interface to the ATmega which modulates a pin connected to a transmitter extracted from cheap RF433 based remote X10

In realraum there are currently two senders:

1. Teensy2 hidden inside lasercut Deckenlichtschalter box next to passageway.
2. OOOllldd Arduino on top of the shelf which also hosts the stereo next to the frontdoor.

golightctrl running on realraum@licht.realraum.at takes care that there they don't send simultaneously.

The presence-meta-event-goroutine tries to diving if someone is present in realraum or not. Various scripts like play-sound-status.py¹⁾ or dostuff_switch_lights.py²⁾ use this information to, guess what, play sounds or toggle the lights or power to boiler and tesla.
