Review on 🌡️ Ubibot WS1 WiFi Temperature Humidity Sensor and Smart Monitor with External Probe Support, Alerts & History, Free IoT App/Web Console, IFTTT, Alexa, (2.4GHz WiFi – No Hub Required) by Robert Toomey

This is a great solution for monitoring the environmental conditions of ships in port. Customers can even know when the boat descends and emerges from the water. In addition, the temperature of the bilge is perfectly regulated. They're great for any type of gear that's less than a few days away from permanent storage. Including airplanes. You can even set motion notification alerts. We will buy dozens more. The web interface is very functional and included in the price. If you want free SMS alerts, ask the server to send an SMS to your email address (just send a Google email to SMS with your carrier name).
