What is Octopus?

Octopus is a multifunction IoT device based on ESP32 designed for remote monitoring and control. It combines local visualization (display) with sensors and actuators, and integrates with platforms through secure MQTT.

3‑Step Setup

1) Power on holding buttons A and C to enter AP mode. 2) Connect to Octopus (password octopus123) and open http://192.168.4.1. 3) Configure your 2.4 GHz WiFi and save. The device will reconnect automatically.
