It’s not as cheap as it was earlier but still cheapest at this moment.
The HS100 allows you to create schedules to automatically power on or off your home electronics and appliances at anytime. You can create a schedule for each device any day of the week, or customize it by a specific time in a day.
Keep energy bills low by effectively managing devices that use the most power. Scheduling allows you to prevent power-hungry devices from being left on longer than needed.
Have your devices run on your schedule, even when you’re not there.
30/12 Mod: Available again. Thanks Xyzzy
Cheap but remember it's the HS110 that can monitor your power usage… i got another one at Bunnings a few days ago for $39 not on sale.
