Smart heater

Smart thermostat using an esp8266. I made this in order to make my heater "smart".

It uses a tiny i2c oled to display the current state.

Features:

• Physical control with 3 buttons
• Control throught mqtt
• The mqtt topics and payloads are compatible with home assistant
• Sync feature (So you can have multiple heaters in one room and control them as if they were one)

Parts:

• Solid state relay(SSR) or standard relay.
• 0,96 inch i2c oled display.
• Esp8266 microcontroller
• ds18b20 temperature sensor
• 3 push buttons
