Power Failure SMS Notification Alarm System

Get notified when power outages occurs..

Powalert® is a plug-in sensor that monitors power outages & temperature. It uses a SIM card to send real-time text message alerts over the GSM (mobile) network.

Powalert is simple to install and very easy to use, just plug it in and use the free app to configure... it’s as easy as that!


Powalert will send a text message alert straight to your mobile phone as soon as there is a power cut or when the temperature gets too low/too high.

Product Description

All the temperature thresholds are user-programmable so you can decide what temperature triggers a text message alert and up to 5 users can receive alerts. Powalert is a completely wireless remote sensor, it only requires mains power and a SIM card to operate.  

Powalert has an internal temperature sensor and also a 1m external temperature sensor for monitoring more specific areas (both temperature sensors can send alerts).

Key Features

  • Monitors key environmental elements (power & temperature)

  • Instant temperature alerts (user programmable thresholds)

  • Instant power outage alerts (and power restore alerts)

  • All alerts can be sent to one or multiple users

  • Remote temperature collection

  • Plug and play

  • Simple control commands

  • Monitor a single device

  • Monitor multiple devices/locations

Temperature and power can be critical for many industries and applications, including: Second Homes/Holiday Homes, Pharmaceuticals & Life Sciences, Hydroponics, Utilities, Healthcare, Marine & Aquatics and Food & Drink Production. Within these industries Powalert can be used for power loss of fridges/freezers, monitoring temperature of perishables, looking after the elderly in winter, monitoring the power of any critical equipment, temperature and power monitoring of IT & communications equipment, power loss for marine & aquatics.


Low running costs

As Powalert only sends SMS’s (text messages) the running costs are extremely low.


SIM/network choice

Powalert needs a SIM card to operate, you can use off the shelf PAYG (pay as you go SIMs). Powalert can only communicate by text message and as it’s a mobile network dependent product we recommend you use the mobile network with the strongest signal where you intend to use Powalert. Powalert is open to all networks.

If you choose to use a PAY As You Go Simcard, please ensure you send a SMS to Powalert every few weeks/once a month (for example a temperature status request) because if the SIM card is not used for several months, the cellular network operator can sometimes take the mobile number back if it’s not being used regularly.


No dangerous lithium batteries

Powalert don't contain dangerous lithium batteries (it uses ‘capacitance’ to store enough energy to send text alerts when the mains power is lost)
