Product Description
The Shelly Plus Uni is a compact smart universal module featuring two potential-free solid-state relays, a pulse counter, one analog input, and two digital inputs. It enables remote control of electrical devices via mobile phone, tablet, PC, or home automation systems. The device can operate standalone on a local Wi-Fi network or be controlled via cloud-based services. It can be accessed, controlled, and monitored remotely from any location with internet connectivity, provided it is connected to a Wi-Fi router and the internet. An embedded Web Interface allows for monitoring, control, and settings adjustment.
Firmware Updates: The device comes with factory-installed firmware. Shelly Europe Ltd. provides free firmware updates to keep the device up-to-date and secure. Updates can be accessed via the web interface or the Shelly Smart Control mobile application. Users are solely responsible for installing updates.

Installation Instructions
WARNING! Danger of electrocution! Do not connect the Device to voltage sources higher than specified.
CAUTION! Use the Device only with power supplies and appliances compliant with all applicable regulations. Short circuits may damage the Device.
CAUTION! Do not connect to appliances exceeding the maximum load.
CAUTION! Connect the Device only as shown in these instructions. Other methods may cause damage or injury.
CAUTION! Ensure the PCB is not in contact with conductive materials during mounting.
CAUTION! For indoor use only. Keep away from liquids and moisture.
CAUTION! Do not use if damaged. Do not attempt self-repair.
General Connection: Connect the Device according to the wiring diagram. Power can be supplied via VAC 1 and VAC 2 (8-24 VAC or 9-28 VDC) or via +5 VDC and GND (stabilized 5 VDC, e.g., from a USB port).
Sensor Connections: You can connect up to five DS18B20 temperature sensors or a single DHT22 temperature and humidity sensor simultaneously.
Input Measurements: The ANALOG IN terminal can measure voltage levels up to +30 VDC (referenced to GND). The COUNT IN terminal can measure signal frequency. IN 1 and IN 2 are digital inputs.
Note: COUNT IN, IN 1, and IN 2 are triggered by voltage levels below 1.5 V.
