Presentation
This project is a IOT hardware heater controller for floor heat cumulating heaters (not sure about english term). These heaters where mainly installed in France. The principle is to store heat in the concrete floor during nights (when nuclear plants are free) to be restored during the day.
The heater can be controlled using MQTT using a Wi-Fi connection or using the integrated OLED display. It is designed to be mounted on a DIN rail in an electrical cabinet.
Hardware
Hardware design files are located in the hardware folder. Schematics and PCB is designed using Kicad.
Software
Microcontroller firmware is located in the software folder. This is a PlatformIO project.

Questions
How big is the Heating controller PCB?
It measures 81.9 × 85.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Heating controller use?
36 parts, built around the AMEM5-5S277HAVZ-B, H11AA1, 1N4148WS and AO3400A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Heating controller KiCad files?
From the BwanaFr/heating-controller repository on GitHub, at the commit this page was made from: the board is hardware/heating-controller/heating-controller.kicad_pcb and its schematic hardware/heating-controller/heating-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Heating controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask BwanaFr before reusing the design.
