UbiBot WS1 Pro WiFi Temperature and Humidity Sensor – Wireless Thermometer and Hygrometer, Freezer Data Logger, Remote Monitoring, Alert Notifications, Compatible with IFTTT and Alexa, Micro USB

良い商品です

会社の保冷庫の温度管理に利用しています。 設定取説は非常に簡単な記載ですが問題なく設定できました。唯一、外部センサーの温度設定をアプリに反映させるのに手間取りましたが結果オーライです。アラート通知は細かく設定ができるのが便利ですが、日本ではショートメッセージや通話通知は出来ないのは残念です（有料版にすると出来るのかもしれませんが）。 アラートは温度異常だけでなく、本体電池切れによりクラウドに通信が届かない場合にもアラート通知が届くので非常に便利だと思います。

倉庫温度のモニタリング用で購入。セットアップがとても簡単で、今のところ問題なし。アラーム機能も付いているので、アプリで温度と湿度の遠隔監視ができます。お勧めです。

mit dem externen Sensor, einfach super, sehr leichte einbindung in das Netzwerk und in die Handy App. Ist sein Geld auf jeden fall Wert.

Need 5 GHz WiFi

Muy buen equipo excelente fácil de configurar y operar

I installed the device in the basement of an unoccupied house, along with an industrial dehumidifier and a 15amp smart plug with power monitoring. I configured the smart plug to run the dehumidifier during hours when electricity is cheap (it uses lots, about $125/month) and the humidity monitor allows me to turn it on and increase the working hours if necessary. I check with my cell phone daily and can see the humidity start dropping at 7pm and temperature start rising (dehumidifiers create a lot of heat); then by morning when the dehumidifier shuts down, the temperature drops and humidity rises. It's predictable, precise, perfect. I haven't figured out how to download graphs from the web interface yet but haven't tried very hard because I don't need them. I use a smart WiFi net and was concerned I'd have trouble getting it on the right band; nope. It just saw the signal (an Asus mesh) and worked.

To monitor the temperature and humidity in the grow room, I searched through Amazon and finally decided to try with this product. The device is worth its price because it is reliable for providing accurate readings. The app provided for the device is very easy to operate. It is really useful that alerts can be sent via emails, app and IFTTT notifications for free. I combined the three modes for each rule just in case I missed an alert. Didn't try with SMS and voice call alerts as they are paid services. BTW, The support said it's better to use external probes for humidity 90% and above.
