PIR Sensor to MQTT - Raspberry Pi, Orvibo wifi power socket

Typically this flow is used to switch lights by means of Orvibo wifi power switches.

The PIR sensor output is 1 when it sees movement and 0 when it doesnt. It has adjustable sensitivity and "on time" by means of potentiometers.

There is also a period after it goes to 0 when the sensor will not recognise movement (the "Insensitive time" or Ti). On my sensor this is about 7 seconds.

This flow seeks to avoid the lights being off and unresponsive during Ti.
