Shelly The Pill
- Microscopic Form Factor: It is one of the smallest fully functional ESP32-C3 smart devices available, fitting into tight spaces where traditional smart relays cannot.
- USB-C Native Power: It plugs directly into standard 5V USB ports or phone chargers, eliminating the need to wire dangerous high-voltage lines for basic sensing tasks.
- Massive Sensor Support: It acts as a bridge for up to five DS18B20 temperature probes or a DHT22 humidity sensor, making it incredibly cheap to monitor multiple zones (like server racks, multi-room setups, or industrial liquids).
- Bluetooth Gateway: It extends your home automation network by acting as a range extender and local hub for Shelly’s line of battery-powered BLU buttons, door/window sensors, and motion detectors.
- Modular Add-Ons: It features a snap-on expansion header that lets you easily attach specialized add-ons (like 30V analog readers, dual SSR relays, or Modbus RS485 communication) without soldering.
- Advanced Gen3 Edge Computing: It runs full custom scripts locally, meaning it can handle complex logic, automate actions, and talk to your Home Assistant setup via MQTT or WebSockets entirely offline.
