TP-Link Tapo Smart Temperature and Humidity Sensor T310, White, Requires Tapo Hub, High-Accuracy Swiss-Made Sensor, Real-Time Notifications, Free Data Storage, Long-Lasting Performance

This unobtrusive little thermometer/hydrometer is perfect for keeping an eye on my Montana mountain home when I am away for the winter-- that's my plan, anyway. When I was renting it out, the house ran out of propane when it was between tenants, resulting in pipes freezing and $50k worth of water damage. I'm not going to let that happen again. I've just ordered a Tapo smart door lock so I can let someone in remotely should the need arise. The Tapo IoT ecosystem is excellent-- they don't force you to buy a subscription to basic functionality out of your gear like ESeeCloud or whatever they are calling themselves now. The Tapo app displays the temperature and humidity in a nice 24 hr graph, which converts to a high/low bar graph when viewing monthly or annual data. I wish you could view historical data in the 24 hr graph format but that doesn't appear possible at the moment. I wondered why it was necessary to use The Hub with this device but it just occurred to me: for non-camera devices, the data storage requirements are small. The hub allows to you have multiple thermometers, water (leak) detectors, etc., that share the same memory device-- no need to buy SD cards for every device, just buy one (big) card for the Hub and you are good to go.

The TP-Link Tapo Smart Temperature and Humidity monitor is easy to setup with the Tapo app (free download) and hub (sold separately). The unit has a very large e-Ink display that is clear to see at various angles. Note though that it needs ambient light, since there is no internal backlight for night visibility. Besides the Temp/Humidity there is also a small battery indicator useful for preventing unexpected outages. In the Tapo app the sensor shows not only the current values but also a plot of Temp/Humidity vs. time for checking how the room climate is changing with time. Additionally, a comfort zone (min/max T and R.H. values) can be defined in the app, so that the app sends push notifications when the room climate is out of the comfort zone.As part of the Tapo smart system, the Temp/Humidity monitor can be used to set up smart actions with other Tapo devices, such as switching a Tapo switch on/off to control a fan or small space heater based on room temperature variations. Overall the TP-Link Tapo Smart Temp/Humidity monitor is an excellent addition to smart home automation projects.

I've tested a number of temperature / humidity sensors, they all had failed miserably. The TP-link Tapo sensor is awesome, extremely easy to set up (you do need a Tapo hub). I connected it with Alexa and set up a routine to control ventilation fans to the built in refrigerator. It works seamlessly and controls temperature great. I read some negative reviews regarding accuracy, so I tested it against the temperature control inside the refrig, it varied by only .1 degree F. Over the past 7 years I've converted the house to total automation (garage door control via vehicle and phone, smart irrigation of lawn and plants, motion sensing light control, smart HVAC systems, smart outlets, smart light bulbs, smart switches), trying a multitude of brands and throwing away a number of devices that just didn't have the quality or features required. I have refined my system down to Tp-Link / Tapo / Kasa, Tailwind and B-hyve for my home automation.

Tapo Hub required. Not a big deal, though, because the hub is cheap. These temp and humidity monitors are not cheap - but the high quality (including the excellent screen) and app-connectivity make it worth it. I find these more consistent and accurate than most cheaper temp and humidity sensors, too. We have four in total. The ability to look at trends in temp and humidity throughout a 24 hour cycle in several places in your home helps a lot with heating, A/C and humidification strategy. No regrets on this purchase, especially as it's a natural extension of the excellent Tapo smart home system we already enjoy.

So far so good. The device is affordable, easy directions, setup took 2 minutes. I LOVE having a widget on my homestretch showing temp and humidity!!! Having fans kick on automatically (I also ha e TP LINK KASA smart plugs) before it even gets hot to circulate air is just awesome. I also love asking alexa what the temp is in the upstairs rooms etc.I also plan to use the same sensors with heater in the winter. Only using them at certain temps means less energy bills.

Easy to setup and use.

Love how it's now very affordable to buy into an ecosystem that enables automation triggered by temperature and humidity. I have 2 TP-Link Kasa plugs attached to a heater and a humidifier respectively and one of these + a hub was all I needed to get smart switches to actually behave smartly and keep my child's room within a temperature and humidity range. The OLED screen has wonderful contrast, compared to my Govee hygrometers that I owned prior and now use as a comparison to see how accurate they are. They match each other within 0.2-0.3 F / 1 % humidity. Time will tell how long they last but I fully expect them to last as long as they say they will.
