The overnight number most houses have never looked at

Turn everything in the house off tonight and the meter keeps ticking over anyway. That's the standby load: the modem, a couple of TVs, the console that's off but still listening for a controller, the soundbar, the printer, and whatever's been plugged in out in the garage since 2019. None of it looks like much on its own. Together, plenty of homes idle at a constant 40 to 80 watts, day and night, all year. At the average tariff of roughly 33c per kilowatt hour, a constant 60W draw works out to about 526kWh a year, which is roughly $173. That's the assumption stated up front, and you can rerun the sums against whatever rate is on your own bill.

The problem isn't that people don't care, it's that nobody actually knows which device is the culprit. Households blame the beer fridge, and half the time it turns out to be a fifteen-year-old set-top box or a pool controller nobody has touched in years. Guessing leads to the wrong fixes: I've watched people replace a fridge that was fine while the real offender kept drawing quietly two rooms away. A metering smart plug ends the argument. You plug the suspect into it, leave it for a day or a week, and read the number in the app. Every pick below has energy monitoring built in, ships new from an AU seller on Amazon, and costs less than the mistake it's there to find.

Why the metering matters more than the switching

A smart plug without a meter is a remote-controlled timer. Useful, but it only automates what you already believe about the house. The metering version is a diagnostic tool, and that's a different class of purchase. It tells you the TV bench draws 22W doing nothing, that the second fridge costs more per year than its contents, or that the dryer everyone blames is actually innocent. Once you have the numbers, the fixes are usually boring and free: a switch gets turned off at the wall, a schedule gets set, one appliance gets retired.

There's a second layer to this. A plug meters one appliance at a time, which is exactly what you want for hunting a specific suspect. If you'd rather see the whole switchboard at once, that's a different device, and I've already covered the clamp-style units in the guide to whole-house energy monitors. The two work well together: the switchboard monitor tells you the house idles high, the plug tells you which socket is responsible. Starting with a single $23 metering plug and moving it around the house each week is the lowest-cost version of that audit, and for most homes it's enough.

The switching still earns its keep once the measuring is done. A plug that's shown you the entertainment unit draws 30W overnight can then be scheduled to kill that circuit at midnight and bring it back before anyone's up. That's the pattern I'd push you toward: measure first, automate second. Doing it in the other order is how people end up with a drawer of smart gear and a power bill that hasn't moved.

What to look for on the listing

The spec sheet on a smart plug is short, so the few numbers that exist matter. The load rating is the big one. A standard Australian socket is 10A, which at 240V is 2,400W, and every plug in this list is rated to that same 10A ceiling. That means the plug isn't the weak link on paper, but it also means there's no headroom: a 2,400W heater through a smart plug has the relay working at its limit every time it switches. I'll come back to that.

• Metering with history. Real-time watts is a party trick. The useful data is the daily and monthly history, because standby waste only shows up over time. All five picks log history in their apps.
• 2.4GHz Wi-Fi. These plugs join 2.4GHz networks, not 5GHz. If your router merges both bands under one name, some plugs sulk during setup. A separate 2.4GHz SSID fixes it.
• RCM compliance. Mains gear sold here should carry the Australian RCM mark. Established brands like Meross, TP-Link and Eve do the paperwork. The no-name marketplace plugs are where that gets murky, and it's mains voltage in your wall, so I don't gamble on it.
• Local control. Ask what happens when the internet drops or the maker's cloud dies. The Meross units run offline routines locally, and the Eve doesn't use a cloud at all.

Build material gets a mention because the listings raise it: the Meross plugs are moulded in V0 flame-retardant plastic, which is the self-extinguishing grade. That's not a licence to run them hard, it's just the right material for a device that lives on mains power behind a couch. While you're reading listings, note who's actually selling. Everything here ships either from Amazon AU itself or from the brand's own AU storefront, and I'd hold any smart plug purchase to that standard, because grey imports with foreign pin adaptors have no place in an Australian wall.

Matter, Thread and whether you need a hub

The plain Wi-Fi plugs here, the standard Meross units and the Tapo pair, need nothing but your router and their own app. Setup is a few minutes over Bluetooth and 2.4GHz Wi-Fi, and voice control through Alexa or Google works once the accounts are linked. For a standby audit, that's the whole requirement, and it's why the $23 Meross is where I'd point most people first.

Matter is the newer path, and it changes the shape of the purchase. The Matter versions of these plugs, the Meross Matter twin pack and the Eve Energy, don't talk to your phone directly in day-to-day use. They join your home through a Matter hub: an Echo, a Google Nest hub or an Apple TV class device, per both listings. The payoff is that the plug stops caring which ecosystem you run. Buy it for an Apple house, move it to a Google house later, it comes along. The Eve goes a step further with Thread, a low-power mesh radio, and per its listing there's no Eve cloud and no account registration at all, which is the most future-proof arrangement on this page.

My honest read: if you don't already own a hub, don't buy one just to run a smart plug. Get the Wi-Fi version, do the audit, and let the ecosystem question wait, because a hub bought for one plug is the tail wagging the dog. If you're already building out a mixed smart home on a plan, and I've written about doing that without wasting money in the smart home on a budget guide, then the Matter units are the ones that won't need replacing when you change platforms, and that's where the extra spend starts making sense.

What a smart plug shouldn't be asked to do

The relay inside a smart plug is a mechanical switch, and switching is when it wears. Small loads barely register. Big resistive loads, which mostly means heaters, arc the contacts a little every cycle, and an automation that flicks a 2,400W heater on and off all winter is a relay endurance test. Metering a heater is fine and genuinely useful. Scheduling one through a smart plug every day for years is where I'd expect the plug to fail first, and a heater circuit is the worst place for a welded-shut relay. If winter heating automation is the actual goal, a hard-wired solution installed by an electrician is the version of that idea I'd put my name to.

The other rule costs nothing: the plug goes into the wall socket, not into a powerboard, and especially not with a heater behind it. Powerboards and their protection circuits are their own subject, and I've been through the joule ratings and failure behaviour in the surge powerboard guide, but daisy-chaining high-draw appliances is how boards cook regardless of brand. Fridges are a softer case. Metering a fridge is one of the best uses of these plugs, because an old chest freezer with a tired door seal shows up instantly in the daily kWh figure. Just think twice before automating the switching on anything that keeps food cold, since one failed reconnect costs you the contents.

How to run a standby audit over a weekend

Here's the method I give customers, and it takes ten minutes of effort spread over a week. Day one, the plug goes on the entertainment unit's socket, everything in its normal off state, and you note the overnight draw the next morning. Day two, the modem and network shelf. Then the garage, the second fridge, the office desk, the washing machine. You're not watching live watts, you're reading the accumulated kWh each morning, because a device that pulses (a fridge compressor, a printer waking to check ink) lies to a live reading and can't lie to the daily total.

Then you do the arithmetic, with the assumption stated: at roughly 33c per kilowatt hour, every constant watt of standby is about $2.90 a year. A TV bench idling at 25W is roughly $72 a year. A forgotten desktop PC sleeping badly at 40W is about $115. Those numbers are what turn the audit into action, because 'the soundbar draws a bit' moves nobody, and 'the soundbar corner costs $70 a year switched off' gets the powerboard switched at the wall every night. I've written up which whole-of-house changes actually shift an Australian bill, and which are gimmicks, in the smart home power savings breakdown, and the plug audit is step one of that.

One warning from experience: expect an anticlimax somewhere. At least one device you were sure about will measure at 2W and be fine. That's a good result. The audit's job is to aim your effort at the two or three sockets that matter, not to justify a purchase you already made. Write the readings down as you go, because in six months, when the next bill argument starts, the notebook settles it in thirty seconds.

Where the plugs themselves die

Smart plugs are simple boards: a switch-mode power supply dropping mains to a few volts, a Wi-Fi module, a relay, and a metering IC watching a shunt. When the branded ones fail, it's usually the relay after years of switching a hard load, or the little power supply drying out after a life spent warm. The no-name versions fail in less polite ways, which is a pattern familiar from the counterfeit chargers I've pulled apart in the bad chargers write-up: creepage distances that don't exist, solder bridges near the mains side, heat-stressed capacitors doming inside a case with no vents. The purchase price difference between those two classes of hardware is about the cost of a takeaway lunch, and the difference in what they're doing inside your wall is not.

The other way these products die has nothing to do with electronics. The maker shuts its cloud down, the app gets abandoned, and a working plug turns into a paperweight because it can't be set up on a new phone. That's why local control sits in my checklist above, and it's a genuine argument for the Matter and Thread units: their control path belongs to the standard, not to one company's server staying up. If a plug of yours has already dropped off the network and re-pairing hasn't fixed it, it's rarely worth bench time on a $23 device, but if it took something valuable with it when it failed, that's a different conversation and you can bring the casualty into the workshop in Erina for a proper look.

Side-by-side comparison

What we see fail at the bench: smart plugs

Smart plugs are simple boards, which is why the failures are so consistent. Inside the case there's a small switch-mode power supply, a Wi-Fi module, a metering IC reading a shunt resistor, and one mechanical relay doing the actual work. Three failure patterns cover nearly everything that goes wrong with them, and only one of those patterns is really about electronics wearing out.

Decision tree: which one should you actually buy?

• Just want to find out what's chewing power overnight? → The Meross single at $23. Move it socket to socket for a fortnight and you'll know exactly where the house stands.
• Want one meter for diagnosis and one everyday smart switch? → The Tapo twin pack at $37.90: the P110 does the metering, the P100 handles the lamp schedule.
• Instrumenting several problem corners of the house at once? → The Meross 4 pack at $69.99, which works out around $17.50 per metered plug and reads all four in one app screen.
• Building the smart home on Matter so nothing's locked to one ecosystem? → The Meross Matter 2 pack at $55.99, provided a Matter hub already lives in the house.
• Apple Home or Thread household, or just don't want consumption data leaving the building? → Eve Energy at $69: Matter plus Thread, no cloud, no account, per the listing.
• A device died at the same moment a plug, board or charger let go? → Stop plugging it into things and bring it in to our Erina workshop. We'll tell you what actually failed, and whether it's worth fixing, before you spend anything.

Frequently asked questions

How much standby power does a typical house actually waste?

More than most people guess, less than the scariest headlines. A constant 60W of standby, which is an ordinary figure for a home with a modem, two TVs, a console and a few chargers, comes to about 526kWh a year. At an assumed average tariff of 33c per kilowatt hour that's roughly $173 annually. The honest answer for your house needs measurement though, which is the whole point of a metering plug: every constant watt costs about $2.90 a year at that tariff, so a week of readings turns straight into dollar figures.

Can I run a heater through a smart plug?

Metering one, yes, and it's a genuinely useful thing to measure. Scheduling one every day, I'd avoid. A 2,400W heater sits at the full 10A rating of both the plug and a standard Australian socket, so the relay inside is switching at its design limit each cycle, and relay contacts pit and can eventually stick under that kind of arcing. A heater circuit is the worst place for a switch that might weld closed. And never run a heater through a powerboard, smart plug or not; wall socket only.

Do smart plugs keep working when the internet drops out?

It depends on the model, and it's worth checking before you buy. The Meross plugs in this guide state on their listings that schedules and routines keep running locally during an outage, with control still available from the app on the same network. The Tapo listing doesn't describe offline behaviour, so assume its schedules want the cloud reachable. The Matter and Thread units, the Meross Matter pack and Eve Energy, handle day-to-day control locally through your hub, and the Eve doesn't use a manufacturer cloud at all.

What's the difference between a smart plug and an energy monitor?

Scope. A metering smart plug measures one appliance at whatever socket it's plugged into, which makes it the right tool for finding a specific culprit. A whole-house energy monitor clamps around the mains in your switchboard and shows the entire property's draw in real time, which is better for spotting that the house idles high in the first place. They complement each other: the switchboard number tells you there's a problem, the plug tells you which socket owns it. If you only buy one, the $23 plug is the smaller experiment.

Do I need a hub for a smart plug?

Not for the plain Wi-Fi models. The standard Meross plugs and the Tapo pair connect straight to your 2.4GHz Wi-Fi and work from their apps with no other hardware. The Matter models are different: the Meross Matter pack and Eve Energy join your home through a Matter hub, which their listings specify as an Echo, Google Nest hub or Apple TV class device, and the Eve also uses Thread. My rule is simple: if you don't already own a hub, buy a Wi-Fi plug and let the ecosystem decision wait.

Will a smart plug actually pay for itself?

In most houses, yes, but through what it finds rather than what it switches. The plug itself draws a watt or so, and its scheduling might trim a few dollars a month. The real return is diagnostic: finding the second fridge that costs $150 a year, the always-on desktop, or the entertainment corner idling at 25W around the clock. One good find repays a $23 plug many times over. If a week of measuring turns up nothing, that's still worth knowing, because it stops you spending money fixing a problem the house doesn't have.
