– WiFi Thermometer Hygrometer, Smart Temperature Monitor Wireless, Humidity Meter Sensor Remote, with Alert/App Notification, Compatible with Alexa, STH51, 1 Pack, SBS50 Base Station Required

I bought the base station with 3 thermometers package, plus, separately, four water leak detectors and a smoke/CO alarm, in order to monitor a temporarily unoccupied house. First impressions are really good - the products feel high quality, the instructions and voice prompts are clear, and setting everything up was quick and easy. All batteries are included which is nice. The app is clear and easy to use without being "dumbed down". A test of a water leak detector proved that the phone notifications are very quick. Having set everything up on my phone, I asked a relative to install the app and make an account or their own, and then added their account to my setup, so now we will both get alerts if there is a water leak, or smoke, or if the temperature goes below or above the range that I configured. It's early days but so far I am really pleased and impressed with this gear

A really, really very smart product. The usual tiny-writing instruction manual...but other than that, nicely packaged; pretty intuitive set-up. Everything worked bang on as it should. The App is well designed (OK with some ads). The resulting data, though, is brilliant. Assuming the readings are accurate which I have no reason to doubt. Good product and good value.

Very pleased, this worked right out of the box, exactly as described, connected flawlessly to my wifi and set up all connected devices to the base station in just a few minutes and is now happily collecting stats. The setup was quick and easy. I installed using Android not iOS, the app is working great. Can't say fairer than that :-)

The sensor is as well made and easy to connect to the base station as others of this make, in my case smoke and CO detectors. Real time indications of temperature and relative humidity are clearly displayed in the app, and historical data can be read from the graphs. The resolution of temperature is 0.1°C, but humidity readings are coarser and the resolution appears variable, with 48.8%, 51.2%, and 52% being indicated, but no figures in between; the graph is rather angular. This is only disappointing because the system in other respects works so well. The alarm functions work as they should, and limits for temperature and humidity are quickly and easily set in the app. This is useful, reminding me to close my elderly mother’s bedroom door to keep the room warm, if she forgets to do so. It would be very useful if these could be interrogated by other home automation systems, eg Smart Life, but I don’t think this is currently possible.

Very clear screen easy to read from a distance. Very easy to connect to the hub and set up. The range for connecting to the hub is the best I've seen. Well designed and sits nicely on a flat surface. Don't quite know what all the humidity readings mean, but I didn't intend these to go in a greenhouse. I am buying another pack of three to cover the whole house.

So far they are proving an excellent product, easy to set up and appear accurate.

Good product. Wasn't sure if the hygrometer part would work,but when you clean a counter with spray near them they set the base unit alarm off. Want to put them all around the house but is that getting obsessive?....

Bought these to monitor the temperatures in my tortoise tabletop viv. Simple and straight forward to use. Connect the base module to WiFi and download the app. Places the thermometers in different places and can monitor when away from home. Well worth it and does exactly what I was looking for.

Easy to attach to the hub. Directly visible on the app. Temperature can be read remotely. So far so good.

Esta muy bien. Controlo desde casa la temperatura y umedad que tengo en un almacen de trabajo.

Très bon produit facile à installer, efficace

Piacevolmente sorpreso della facilità di installazione e accoppiamento con hub ottimo

Pour l'instant, très satisfait, installation facile, données qui me paraissent fiable, en revanche, il est un peu ennuyeux de devoir investir obligatoirement dans la station de base pour pouvoir utilisé le thermo-hygromètre. Fiabilité à vérifier dans le temps
