Review: 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.
