# Remove Homie Device from MQTT
#
# Simple Script to remove all reatined messages for a homie device, effectively removing the device from MQTT.
# The script get all topics "below" a device e.g homie/a020a615f72c/$mac and
# send a NULL message with mosquitto_pub to the topic. This removes the retained
# message and the topic will not show up anymore.

# How?

Fix space removal so that it doesn't break space-separated values where the developer used more than one space to separate values.

OpenHAB Heating Control Rules
OpenHAB Heating Example
========================
This heating example shows three rooms in my house with 1 radiator valve, 1 temperature sensor per room and a single boiler. It could be adapted for different situations.
The rules allow for simple addition of items in rooms as long as they follow the naming convention and have at least a valve, a thermometer, setpoint and a demand switch.
The demand switch is purely internal and is used to indicate if the room requires heat or not. All rooms are OR'd together to define the boiler status and each room demand (On/Off) is applied to the radiator valves.
It could be more generic for multiple thermometers/valves per room - but it suits my needs for now. If I make it more generic I will update it accordingly.
