About this product
The Pill by Shelly is an ultra-compact Gen3 input and output module that runs on just 5V over a USB-C port and weighs around 3 grams. The device turns any wired sensor or low-voltage actuator into a connected part of the smart home over Wi-Fi and Bluetooth.<br><br>Three configurable channels let you attach up to five DS18B20 temperature probes or a DHT22 temperature and humidity sensor, read 0–2.5V analog voltage, and drive digital inputs and outputs with 3.3V logic. The built-in Bluetooth gateway relays data from Shelly BLU devices, while MQTT, WebSocket and HTTP support opens integration with third-party systems.<br><br>The module works with the Shelly app, Home Assistant, Google Home and Amazon Alexa, and supports scripts, schedules and webhooks. Its compact shell fits inside a distribution board or a DIY project enclosure in Chisinau.

Up to five DS18B20 probes measure flow and return temperature of the boiler.
During frequent outages the owner sees the battery level in the Shelly app.
With the 0-30V add-on the module measures the UPS battery voltage.
In an apartment The Pill collects readings from BLU door and temperature sensors into Home Assistant.
The Bluetooth gateway relays Shelly BLU sensor data without a separate hub.
