Power Failure Detector with 3 added sensors:  Water, Temperature and Continuity



Enjoy all the benefits of the Power Failure Detector with 3 added sensors:  a Water Detector,  a Temperature sensor, and a Continuity (or Short) Detector.


The added high-quality waterproof temperature sensor can be operated in two modes. One mode sends alerts when temperature goes above or below your thresholds. And the second mode collects and displays data so that a chart of the last 24-hour temperature measurements is available on your private page on myspool.com after you login, under MY DEVICES. You can also send this data to a ThingSpeak channel for display and analysis. See here for directions on how to setup this free data channel.

Water;and Temperature Alert comes with an extra long 6 ft power cord and two hardened sensors: a water sensor with a 5 ft cable and a temperature sensor with a 3ft cable.High quality moisture sensor has a nickel plated surface for corrosion resistance. It is designed for multi use: just wipe it dry and use it again. High quality waterproof temperature sensor has a temperature range from -55°C to +125°C (-67°F to +257°F), with accuracy of 0.5°C over recommended range of -10°C to +85°C. All readings outside this range are ignored:-30°C to +105°C or -22°F to +221°F

This device also comes with a 2 ft cable for the Continuity (Short) sensor. This cable can be plugged in the slot marked CONT inside the black enclosure. Short the other ends of the 2-wire cable and you will get an alert. Alternatively, this CONT slot can be used with other MySpool sensors such as the float or the door open sensor.

Customization option: there is another slot marked PWR next to the CONT slot. You can cut the included cable and use the other half in the PWR slot to send a TTL level (5V) signal outside for external power ON/OFF signalling.

Note: Power ON and Power OFF alerts can be sent as a text message, email, pushbullet or any combination of the three. Water, Temperature and Short alerts are sent only as email or pushbullet notifications. 


BASE Power Failure Alert: 

  • Be alerted when power goes out: MySpool P3 uses Wi-Fi to send text messages, email or push alerts when power goes off or comes back on
  • Name each device and send notifications to identify the power outlet affected
  • Each MySpool P3 is independent; no hub is required
  • WiFi access during power outage is required, please check before ordering
  • No fees or subscription costs


Be alerted away from home or business 
MySpool P3 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.  P3 is configured to use your WiFi (see Important Note below). The setup takes a few minutes with a smart phone or a laptop.


No Hub Required 
Each P3 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.


No Fees 
There are no fees for using MySpool P3 for any notifications. P3 purchased on MySpool.com comes with support for 1 telephone number and up to 5 email addresses for alert notifications. To add more telephone numbers without fees, see these directions.


Flexible design 
MySpool P3 comes with an extra long 6 foot power cord connected to an enclosure with a transmitter. P3 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.


Important Note: one requirement for the P3 deployment is that a WiFi network is available when A/C power outlet being monitored loses power. A good example is a UPS backed WiFi router which Power Failure Alert uses to access MySpool cloud servers.
