The Shelly Plus Uni is a smart WiFi-operated module engineered for use in low voltage systems, providing automation and monitoring for a hugely broad variety of applications. Compatible with most Arduino sensors, the Shelly Plus Uni features digital and analogue inputs to measure any parameters and create complex automated scenes based on the data, like activating garden irrigation systems when soil moisture drops below a certain level, or integration with an intercom or alarm system to send updates directly to your phone. Also included is a pulse-counting feature, ideal for close monitoring of electricity, gas or water usage by connecting it to the respective meters.
