Review on 🌡️ YoLink Smart Wireless Temperature & Humidity Sensor - Ideal for Freezers, Fridges, Greenhouses, Pet Cages - Wide Temp Range (-22 to 158 Degree) - Smartphone Alerts, Alexa & IFTTT Compatible - Hub Required by Tonya Greene

I came across YoLink while searching the web for separate smart temperature sensors and smart humidity sensors for several automation projects in my home, so I was thrilled that they had a temperature/humidity sensor have (in single block). As an electronics and home automation enthusiast, I add them everywhere in my house. Here are a few photos, as well as a few applications I've tried or will implement in my home: Automatic control of bathroom exhaust fan - Turn on the fan before the room steams up during a shower/bath. Keep an eye on the fridge. at the final stage, monitoring of temperature and humidity in an aquarium with bearded dragons. Both are very important. I also have an automatic to turn on the heat lamp when it gets too cold. My daughter who is her pet installed the app and gets notifications about temperature or humidity issues. I also have a general fuel gauge on a planned smart plug. I am about to install a whole house fan soon and I would like to use it in most rooms of the house to slow down or turn off the fan and also to control the ceiling fans in the bedrooms (to turn them off when it is gets too cold at night otherwise WHF runs all night). Ceiling fans are installed on Lutron Caseta switches, but Alexa and IFTTT.com integration allow for cross-brand automation. Very flexible! I see an additional use for this in the maintenance of a wine cellar, a leaking basement (in combination with a water sensor), an unoccupied property, a building or a room that could be damaged by frost, extreme heat or humidity (and mold), and others emerging problems). This is a great price too. Which is good because I plan on getting more of these!
