ESP32 Thermostat Ota

This project features the Back End (firmware) of an I.O.T. system that is able to controll any gas heater.

UNIT TEST THE CODE ON THE BOARD (PlatformIO Test) BEFORE COMMITING CODE

Features:

• Serves a react app that consumes the API
• Exposes a number of endpoints that let the UI controll the system
• Exposes a webSocket that lets the UI update in real time
• Can be programmed over the air (OTA) [this way more then one device can be updated without needing phisical acces to it]
• Is resilient to IP changes (if the router assigns a different IP [when it resets for example] to the device it it stil accesible via an URL through mDNS)
• Meajures the ambient temperature every 5 seconds and starts teh heater or stops it ddepending on the settings
• Temperature controll hysteresis (uses the house itself as a thermal battery so that it reduces the wear on the heater)

Planned features

• Switching from enbedding the web page files directly into the firmware (although a perfectly valid option in embedded) to writing the files directly to the flash memmory using S.P.I.F.F.S. [Serial Peripheral Interface Flash File System] - this should enable us to update the served Web App without reprogramming the microcontroller.
