An important consideration to keep in mind when shopping is the power source and battery life of a device. Is it wireless or does it need to be plugged in? If wireless, what type of batteries are needed and how long is the expected battery life? Remote Monitoring and Alerts

The iHome iSS50 does not utilize batteries, unlike the other temperature monitoring devices on this list.

Maximize Comfort & Save Energy

Perhaps all you need is a basic temperature sensor to keep an eye on your house or yard while you’re gone. If this is the case, AcuRite 00782A2 Wireless Indoor/Outdoor is the choice for you. All-Round Compatibility : Compatible with the most popular ecosystems and can be controlled by voice. Apple HomeKit, Alexa, Google, IFTTT, Alice, Marusya are supported. Made in the USA, this remote hygrometer is a precise and versatile option to continually monitor conditions in any environment, from just about anywhere. Unlike some wireless hygrometers, it’s extremely easy to set up in just a few minutes and it’s factory calibrated (you can also adjust the calibration if required). It requires only two AA batteries, and users report battery life between six and 12 months depending on usage. You’ll also get an automatic alert if the batteries are low, to minimize any downtime. Aeotec has managed to include every sensor you would ever need in a smart home, with sensors that can detect motion, temperature, a light and humidity sensor for Z-wave systems, and vibration and ultraviolet sensors.

In addition to sensing temperature and humidity, the iHome iSS50 can detect movement, light levels, and sound.The notifications will appear on the console, where the maximum and lowest values for each sensor will be shown. This makes it ideal for use in an RV, vacation home, or any other distant place where you may not have access to a WiFi network, a mobile hotspot, or the capacity to come on a regular basis to connect to the sensor.

So I went online to look at my options; I wanted a SmartThings capable smart humidity sensor that would integrate well with my smart home. Temperature and Humidity Notification: Aqara Home app ( iOS/ Android) can notify you in case the temperature or humidity has reached a pre-set value. After installing the device handler, add the sensor to your SmartThings hubs as you usually do, and you are good to go.There are many humidity meters on the market, with a wide variety of features, accuracy, and prices. Some hygrometers are basic devices that measure humidity in one spot. Others may include several sensors to monitor the conditions in multiple areas, and some allow for remote monitoring through an accompanying smartphone app. To properly care for the plants in your greenhouse, you will want to monitor the conditions to provide the best environment for your plants to thrive. A greenhouse temperature monitor will help you control humidity levels, particularly as they change during different seasons or times of the day. There is not one ideal humidity level for a greenhouse, but rather it’s important to understand the correct conditions for your own plants and limit any dramatic changes in the conditions, so they do not suffer adverse effects. Accuracy A hygrometer, sometimes known as a humidity meter or humidity gauge, is a device for measuring humidity in the air. In other words, hygrometers measure the amount of moisture in a particular environment, usually by calculating temperature and pressure changes. There are many kinds of hygrometers, including electrical or digital models, psychrometers, mechanical hygrometers, and dew point hygrometers.
