PLOJOP Power Failure Alarm WiFi 110dB Outlet Monitor

PLOJOP Power Failure Alarm is a plug-in WiFi outage detector that sends instant smartphone alerts, sounds a 110dB siren, flashes a red LED, and runs up to 12 hours on its rechargeable backup battery.

Keep sensitive equipment and perishable goods safe with a compact, easy-to-install device that monitors a standard 120V outlet and notifies you the moment power is lost. Designed for freezers, sump pumps, aquariums, greenhouses, garages, and basements, this alarm pairs with the free Smart Life or Tuya app to deliver push notifications, while also providing loud local warnings and a visible LED indicator so everyone nearby is alerted.

How quickly will I receive an alert when power goes out?

The PLOJOP alarm sends push notifications to your smartphone almost instantly after it detects a loss of power at the connected outlet. Because it uses WiFi and the Smart Life/Tuya platform, you’ll get remote alerts whether you’re next door or miles away.

• Instant push notifications via Smart Life or Tuya app
• Local 110dB siren and flashing red LED for on-site awareness
• Requires manual reset after outage to ensure acknowledgement

What local alerts and backup options does it provide?

Besides remote notifications, the unit gives immediate on-site warnings: a 110dB siren with three adjustable volume levels and a bright flashing red LED. A built-in rechargeable battery provides up to 12 hours of operation during an outage so critical equipment remains monitored until power returns or you respond.

• 110dB alarm with three volume settings
• Flashing red LED for visual notification
• Rechargeable battery offers up to 12 hours of backup power

How simple is installation and everyday use?

Setup is plug-and-play: insert the alarm into any standard 120V AC outlet, install the Smart Life or Tuya app, and follow the in-app steps to connect. The compact footprint makes it unobtrusive, and basic controls on the device let you silence the alarm or perform a manual reset after outages.

• Plug into any standard 120V outlet (3.54" x 1.93" x 1.38")
• Pair with the free Smart Life or Tuya app in minutes
• Manual hard reset required after power interruption for safety

Where should I place this alarm to get the most benefit?

Place the alarm in locations protecting high-risk or high-value systems — such as next to freezers, refrigerators, sump pump outlets, aquariums, or greenhouse power circuits. Because it provides both remote and local alerts, it’s effective in basements, garages, server closets, and anywhere a sudden outage could cause damage.

• Use on outlets serving freezers, sump pumps, and refrigerators
• Ideal for aquariums, greenhouses, and home office equipment
• Works well in basements, garages, and other unattended spaces

Who is this for? Homeowners, landlords, small business owners, and hobbyists who need reliable, immediate notification of power interruptions will benefit from the PLOJOP Power Failure Alarm. If you store perishable food, rely on a sump pump, maintain aquarium life support, or run critical devices in remote or unattended spaces, this compact WiFi-enabled alarm offers an extra layer of protection through instant app alerts, a loud local siren, visual LED warning, and a long-lasting rechargeable backup battery. Note that the device is designed to require a manual reset after outages so every interruption is acknowledged before normal operation resumes.
