## Description

desertcart.com : Shelly i4 Gen3 WiFi Smart 4-Digital Inputs Controller, No Hub Required | Home Automation, Compatible with Alexa & Google Home, iOS Android App, No Hub, Remote Control, Multi-Click, Relays : Tools & Home Improvement

Review: useful and reliable - I got this to connect a 110v beam-break sensor (Seco-Larm E-931-S35RRQ) in order to automate the lights (via Home Assistant and Z-Wave) when walking into our TV room with no windows. It has been essentially flawless and responds instantly and reliably. We do on rare occasion find the lights on unexpectedly in that room, but I have every reason to believe that is more an issue with our sensor installation than with the Shelly.
Review: Typical Shelly product - This is just like my other Shelly devices. It works. I use this connected to four switches to control a 3D printer chamber heater through Home Assistant.

### ⭐⭐⭐⭐⭐ Typical Shelly product
*by J***S on June 2, 2026*

This is just like my other Shelly devices. It works. I use this connected to four switches to control a 3D printer chamber heater through Home Assistant.

### ⭐⭐⭐⭐⭐ Fast communication over local Wi-Fi is reliable.
*by N***. on April 1, 2026*

This works great for detecting the change between "open" and "hot". But it doesn't work to detect the change between "on" and "off" when the off has a pull down. For example, connecting to a light bulb to try and sense when the light has 120v applied vs when it's off. Both the on and the off are connected to something and the device sees both the on and the off as connected - the light's filament is connected to neutral. So this triggers the device to see a connection. I solved this by adding a relay. Now the light bulb energize also powers a relay coil and the Shelly senses the relay closing. Works great.
