Power Outage Alarm


Don’t let a power outage ruin your property!

Learn how to avoid disasters caused by a power outage and get an alert to your phone.

The iSocket 3G is the world’s first 3G smart plug that notifies you of power outages and temperature changes (when fitted with the optional temperature sensor) on either your smartphone or non-smart phone via the 3G mobile network with either Telstra or Optus.


The iSocket 3G notifies you of a power outage and once the power is restored sends a text message to your phone. Utilising high-quality Li-ion re-chargeable batteries, ensures you will receive an outage notification even in the event of a break in the cellular network. The iSocket 3G smart software is able to detect a network break and wait for the signal to return before sending the power failure message. As soon as the message is sent the device will shut down and the battery will be recharged when power is again available.

With an optional sensor connected to the iSocket 3G you can measure: temperature of the air, water, oil, solid surfaces, etc. iSocket 3G will notify you when the temperatures rise above or drop below specified levels. iSocket 3G is equipped will a relay that can turn equipment on or off according to your settings. This can also be done remotely from your mobile phone.

A really useful feature of the iSocket 3G other than power outage alarm is the ability to turn on an appliance remotely. The iSocket 3G has a 3 pin plug on the front of the device to enable this feature.

Please read all the below information before purchasing your iSocket 3G device.

Dewar does not supply the SIM cards to insert into the iSocket so they work. You must purchase these yourself. 

When purchasing your iSocket 3G, you have to choose if you want a Telstra or Optus device. This will depend on the type of SIM you are looking at purchasing/using. If you get a Telstra SIM you can only use this in the Telstra iSocket device. There is an option to select Telstra or Optus when purchasing this. If you do not advise which one you want, we cannot process your order.
