## Description

Shelly H&T Gen3 White | Wi-Fi & Bluetooth Smart Temperature & Humidity Sensor with Remote App Control | Smart Scenes | LCD Display: desertcart.com: Industrial & Scientific

Review: This is a very good H&T device - I am a software developer. I spent a lot of time reviewing different devices, interfaces and their specifications. I wrote software to manage this device, including RPC, Bluetooth and MQTT. I am also very experienced in the dynamics of environmental monitoring for residential and commercial buildings. In my opinion this is an excellent humidity and temperature monitor at a low cost for home automation. The interfaces are well documented, easy to work with and there are numerous open-source implementations and libraries available. If you are a non-developer or a home automation user, this device will monitor humidity and temperature and perform well. I have read comments regarding long times to report changes. Temperature and humidity do not change rapidly in normal residential or commercial environments. If you require fast change detection, you are designing for a problem this device is not intended for. This device reports on wakeup every six minutes. The reason is to save battery life. That is sufficient in normal environments. If you require fast response times, select a different type of device that is plugged into a power source and reports continuously. The device will need to support rapid temperature and humidity changes and those types of instruments are much more expensive. The big issue is accuracy when detecting changes. It does no good to use a cheap device that reports every 5 seconds if the changes are only +-20% accurate. Accuracy requires either time or money.
Review: works via wifi - very helpful in monitoring the temperature at a nearby rental house. I can take a quick look on my app.

### ⭐ Bought six, returned six…
*by J***B on October 27, 2025*

I had great hope for this device. On paper it looked perfect for my use case and I purchased six units. I returned all six after two units failed to operate on battery and a third was intermittent on battery. I did not have time to debug the problem. With that said, registering the device is not clean and simple, and I was able to mess it up, but once configured one unit seemed to work well. Note, to conserve battery power, these devices report temp and humidity once, then power down WiFi and wait for the temp or humidity to change before powering up WiFi and reporting the new values. So if temp or humidity change a lot, then battery life will be shorter. The ePaper display is a great idea if you need to directly see the measured temp and humidity vs checking the app. The app allows you to bias the measured temp and humidity readings, so you can sync the units to one another or another thermostat. This is a useful feature to compensate for normal variations between devices. Again, the device looked good on paper, but the battery issue was killer for me.
