A Raspberry Pi based system that allows the user to control the heating in a house. The primarily Python based system (as part of a Docker container stack) allows users to open 10 switches (via a 240v relay) and 3 x PWM signals for controlling variable pumps or valves. The system is controlled via a Python based API. The management system would POST data to the Pi via JSON. E.g. POST {'switch':3, 'value': false}. I'd be happy to explain more about this in a chat.

A Docker bases system with a SIM router for data recording to the web and to allow external control.
