The BlueMaestro Tempo Bluetooth Smart Temperature Monitor is a cool piece of home gadgetry that allows you to constantly monitor the temperature inside and outside your home and set alarms based on predefined temperature thresholds.
The BlueMaestro monitor works on devices equipped with low energy Bluetooth 4.0 running on Android 4.3 and iOs 6 and higher (check your device’s compatibility here)
Here’s how it works: first, make sure your Bluetooth connection is set to not time out (some smartphones come with connection timeout setup to 2 minutes), instal the free Android or iOs app, hold the monitor’s button pressed for 1 second (you’ll hear a small beep when it turns ON) and you’re ready to roll. That’s it, no setup, no syncing or any other action required. In a couple of seconds the device will start reading information from the monitor.
Both Android and iOs apps will show you temperature stats and will allow you to set triggers based on your temperature preferences. I find this feature very useful as it can help you quickly identify sudden temperature drops or increases and gives you the chance to take action before it’s too late (think about saving those flowers when you forget the window open in the middle of the winter … this actually happened to us while we were testing the device) as well as smaller differences which, addressed in time, can help you cut heating and AC costs.
The Smart Monitor can connect to your phone for up to 75 meters (that’s about 225 feet) if it has a direct line of sight, is weather proof (can be used outside as well as in humid environments), allows multiple units to hook up at the same smartphone or tablet (you can easily monitor multiple rooms at the same time) and is conveniently powered by 2XAA batteries (included) which will last for about 1 year (you can easily change them by unscrewing 2 screws and removing the back cover).
