Be alerted away from home or business<br /> MySpool Power Failure Detector is a smart device that sends an alert when power failure is detected. An alert is also sent when power comes back on. That alert is a message, either via email or text, or both. Power Failure Detector is configured to use your WiFi (see Important Note below). The setup takes a few minutes with a smart phone or a laptop. <br /><br /> No Hub Required<br /> Each Power Failure Detector works independently with your Wi-Fi network. Multiple devices can be placed in different locations throughout your home or business. Your notifications will include your text for each device that you specify in the device configuration. <br /><br /> No Fees <br /> There are no fees for using MySpool Power Failure Detector for any notifications. <br /><br /> Flexible design<br /> MySpool Power Failure Detector comes with an extra long 6 foot power cord connected to an enclosure with a transmitter. Power Failure Detector will ignore short duration power fluctuations of less than 2 seconds so that no unnecessary notifications are sent. Note that since no device is permitted to send more than 1 alert per minute, your POWER ON notification may be delayed by up to 1 minute if power comes back on immediately. Each device requires 3 AAA batteries, included. The batteries should last 5 years or more assuming average power outages and fluctuations
