The MySensors OLED Wall Thermostat project, developed by Damsma, is an open-source project that aims to create a customizable and efficient wall thermostat using MySensors technology. This thermostat integrates an OLED display, various sensors, and buttons to provide a user-friendly interface for controlling home heating systems.

### Key Components:

1. **OLED Display**: Utilized for showing temperature, humidity, and other relevant information. It connects via SPI/I2C interfaces.

2. **SHT-30 and DS18B20 Sensors**: These sensors are used to measure temperature and humidity, ensuring accurate readings for climate control.

3. **W5500 Ethernet Module**: This module is crucial for network connectivity, allowing the thermostat to communicate with other home automation systems over a wired Ethernet connection.

4. **Buttons**: Used for user input to adjust settings and navigate the thermostat's interface.

### W5500 Module Usage:

The W5500 Ethernet module provides a reliable and straightforward way to connect the thermostat to a home network. It handles the Ethernet connectivity, enabling the thermostat to send and receive data from a home automation controller such as Domoticz or Home Assistant. The connections for the W5500 are as follows:

- V+5 -> 5V

- GND -> GND

- NSS -> D10

- MO -> D51

- SOK -> D52

- MI -> D50

This setup ensures that the thermostat can effectively communicate with the home automation system, allowing for remote monitoring and control of the home’s climate settings.

### Additional Information:

The thermostat is designed to fit seamlessly into a home automation ecosystem, providing precise control over the heating system. The project includes detailed wiring diagrams and a parts list, making it accessible for DIY enthusiasts looking to build their own smart thermostat.
