Energy Saving & Less Vampire Power
ST-027 only consumes 0.5w, if you keep ST-027 on for 24h *30 days = 0.36kWh.
Ok ok ok... in English, it means ST-027 only costs only around 6 pence per month. (your device’s power is not included.)
Vampire power is the power your electronic devices use when they are on standby. Vampire or standby power can make up to 10% of your electricity bills. What’s more, standby power use is roughly responsible for 1% of global CO2 emissions!
Reduce your chance of electrical fires
Any electrical appliance has the potential to start fires or cause an electric shock, and each brings with it its own dangers, ranging from frightening to life threatening. A few of the common culprits are toasters, microwaves, clothes dryers and dishwashers.
Ensuring these appliances are switched off using a smart plug whenever you’re not using them will cut down on the chance that one of your appliances will have a fault and catch fire when you are sleeping or out of the house.
How’s that for peace of mind?
Limit your children’s screen time
Tired of the weekday battle of getting your children to do their homework or to go outside for a while? Having trouble enforcing rules on how much TV can be watched, or how long the Xbox or play station can be played? ST-027 Smart plugs can help you manage your children’s screen time and put into place a healthy after-school routine.
Fool Opportunistic Burglars
A large proportion of burglaries are not pre-planned. Rather, they are opportunistic crimes, why not employ ST-027 to control your lights — all you need to do to create the illusion of activity in your house is to tap a button on your smartphone to switch on a light!
Everything on Schedule automatically
You can also create schedules in daily life! Like timer to turn on your coffee maker at 7:30 a.m; keep your kids on schedule to make sure the television is turned off when they should be doing homework, or use a countdown feature to have any lamps shut off right before bedtime.
