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.
Review: Shelly Ecosystem is great in Home Assistant - I really like the Shelly Addon. In my case I am doing something very specific, I am using the addon out doors to monitor the temp of animal waterers. I *could* have built this sensor myself but given the fact that it has a case, and hooks right into the shelly plus devices, this was definitely the way to go over DIY. Sure I could have done it cheaper, but at the end of the day, the temperature rating for these devices and the whole package were a big part of the reason I bought these. Works great with Home Assistant. I don't use the Shelly cloud. I used to flash Shelly devices with Tasmota, but recently the Shelly firmware has gotten quite good and the updates for the firmware show up in the HA dashboard which is a big plus. The add on has a limited number of sensors that it supports so its not perfect, but it fit my usecase perfectly
