USBy v3 … the device that alerts you when there is a power failure

USBy  is an innovative device patented to notify you when the electricity supply fails.
USBy it also warns you when the power supply is restored, reporting the total black-out time.
The alert emails arrive directly on your mobile phone, managed by our Cloud Server (optionally also via telephone call). So even if your WiFi router turns off due to a power failure, the reception of alarms is guaranteed.

USBy allows you a great saving compared to traditional solutions, because  It does NOT need any GSM SIM card or an uninterruptible power supply to work.

– fridge-freezers: you know exactly how long food has been without cooling
– medical devices: you know how long the device has not been powered
– attempted theft: it informs you if they cut the power to disable alarms or video surveillance systems
– aquariums: you know immediately when and for how long the water circulation has stopped

It is simple to use. Works with WiFi.
