## What it is
ESPurna is open-source firmware for ESP8266/ESP8285-based smart switches, lights, and sensors, supporting over 125 devices with sensor integrations and third-party integrations. It is built with the Arduino Core for ESP8266 framework and developed using PlatformIO.

## Use cases
- flash custom firmware onto a Sonoff smart switch
- replace stock firmware on ESP8266 smart plugs
- read sensor data from ESP8266 devices over WiFi
- control smart home lights without a cloud service
- support many different ESP8266 devices with one firmware
- build DIY home automation with cheap smart hardware

## When to choose
- you own ESP8266/ESP8285-based smart devices like Sonoff switches or plugs
- you want local control of smart home devices without vendor clouds
- you need broad device support (125+ devices) in a single firmware
- you want a mature, community-supported alternative to Tasmota

## When to avoid
- your devices use ESP32 or other non-ESP8266 chips
- you need a modern actively developed ecosystem with frequent new features
- you prefer a web-first configuration experience over embedded tooling
- you need integrations beyond what its sensor and third-party support offers
