Description
The device is based on the proven ESP8266 (ESP-12F) module and can be programmed using Arduino IDE, PlatformIO, ESP-IDF (C/C++), or NodeMCU (Lua). It is also fully compatible with Tasmota and ESPHome, providing great flexibility for developers and hobbyists. With native MQTT support, ES.PINIO is ideally suited as an actuator, status, and measurement interface in smart home installations.
