-
Multiple Inputs & Outputs:
- 2 Digital Inputs: For connecting switches, buttons, or motion sensors.
- 1 Analog Input: For connecting a variety of analog sensors (e.g., soil moisture, light intensity).
- 2 Dry Contacts (Solid State Relays): Potential-free outputs that can switch up to 30 VDC and 24 VAC with a max current of 300 mA.
- Sensor Interface: Supports a single DHT22 temperature and humidity sensor or up to five DS18B20 temperature sensors via its 1-Wire interface.
- Precise Voltmeter: Features a two-range voltmeter to measure DC voltage in ranges of 0-15 VDC or 0-30 VDC.
- Pulse Counting: Capable of reading data from energy, gas, or water meters that support pulse outputs, allowing for detailed utility usage monitoring.
-
Connectivity:
- Wi-Fi Operated: Connects to your 2.4 GHz Wi-Fi network without requiring a separate hub.
- Bluetooth Gateway: Uses Bluetooth for quick inclusion and serves as a Bluetooth Low Energy (BLE) gateway for other Shelly BLU devices.
