Easy Smart Thermostat Alternative For Any DIY Enthusiast
I've been using Shelly devices for several years and have been consistently impressed. These add-ons are fantastic! I have one currently controlling my 240V, 3000W electric space heater. It's configured with one leg of the 240V connection (at 120V) running through the relay, which also powers the Shelly 1. This add-on is connected to a standard DS18B20 temperature probe. Using Shelly's virtual thermostat feature with this add-on, I can precisely control my shop's temperature from anywhere with an internet connection via the Shelly app. I also have another one of these units controlling an exhaust fan in a grow room, connected to a DHT20 temperature and humidity sensor. Both add-ons have been working flawlessly. You can use these devices with a variety of sensors, including soil temperature/moisture sensors, and they can be powered by DC as well. This adds tremendous value to Shelly Plus devices! I highly recommend these add-ons for any home automation project. They are easy to configure and use. In the future, I plan to add a display unit and an OpenHab server to create custom widgets showing the temperature and other metrics all in a nice wall display.

Shelly is Great
Shelly is a awesome device, works without issues and connects with home assistant. Setup up a multi sensor that track the duct system of my home HVAC and if the fan is running or not.

Little device with a lot of capabilities
I got this to add on to my Shelly Plus One and it was super simple to add. Just click it in place, and connect a temperature probe the provided terminals. You just need to go to the Shelly Plus One's web UI to enable this, and it'll be off and running. Pretty easy (and cost effective) way to extend a Plus One to have temperature and humidity sensors.

Sensors
Excellent to add temperature sensors and analog and digital inputs to a Shelly relay. I'm using it to control a fridge, several temperature sensors inside the cabinet and a variable resistor to set the desired temperature without using an app

Easy to use
Easy to use. Exceeded expectations. Allowed me to take what would have been a $1,300+ investment and do it for $30!

Produit shelly au top
C'est le deuxième module que j'achète, j'ai déjà toute une gamme de chez Shelly. Comme à chaque fois, très facile à mettre en place et en service. Mesure de trois température pour mes panneaux solaire qui est très précise (1/2 degré) et réelle, avec historique, déclenchement de scénario, de notifications (je reçois un mail dès que la température dépasse un seuil programmé), etc...

Quick and easy way to monitor temperatures
I added this to a Shelly 1 Plus and fitted it with 5 long DS18B20 temperature sensors to be able to check that cold water pipes were not getting cold enough to freeze. The Shelly app shows the data as nice graphs, but I also have them connected to Home Assistant using MQTT, which works really well. It was very easy to install the device by clipping it to the Shelly 1 Plus and wiring in the sensor leads (although the screw terminals are really tiny).
