ANAVI Thermometer is an open source hardware Wi-Fi development board for measuring temperature powered by ESP8266. It comes with a built-in DHT22 temperature and humidity sensor and has slots for mini OLED display, waterproof DS18B20 temperature sensor and slots for up to three additional I2C sensor modules. All these features make ANAVI Thermometer appropriate for developers, makers, students and open source enthusiasts interested in home automation.

ANAVI Thermometer is fully compliant with Arduino IDE, PlatformIO and the popular open source home automation software Home Assistant via the lightweight messaging protocol MQTT. With ANAVI Thermometer it is easy for developers to focus on the software by easily building and flashing their own versions of the source code. Tech savvy users can easily integrate ANAVI Thermometer in their existing open source home automation platforms.

ANAVI Thermometer is an entirely open source project that combines open source hardware with free and open source software. It has been certified by the Open Source Hardware Association under UID BG000017.

The free and open source software tools KiCAD and OpenSCAD were used to design ANAVI Thermometer. Source code and schematics are available at GitHub. All units will be manufactured in Plovdiv, Bulgaria. Getting started with ANAVI Thermometer is easy. No soldering is required. Comprehensive user’s manual with exact steps for using ANAVI Thermometer will be provided.
