Pi-Heating

This is a working replacement for a central heating 'programmer' in a system with a 3-way valve switching hot water between hot water/central heating/both. Software written in Python.
PCB layouts are included, and code for the raspberry pi which controls the heating via a web front-end.

The project replaces the "junction box" that connects boiler, programmer, pump, motorised valve, and thermostats together and makes most of these software accessible. The Raspberry Pi is connected by an umbilical lead using i2c.

WARNING: this involves rewiring mains connections - at your own risk. Be extra sure you know what you are doing!

Features

3 timed on/off settings per day for CH and HW
Override on/off, until a date/time in the future.
Switch off when nobody in the house (by detecting mobile phones on Wi-Fi)
Controlled via web interface, accessible from PC or mobile phone
Log of activity, for possible historic analysis
Designed to fall back to 'old' programmer switch in the event of most software and some hardware failures
