7 smart home automations that work better with NFC tags than motion sensors or schedules


There are plenty of ways to trigger smart home automations. Schedules are great for things that you need to happen at the same time each day, and motion sensors are a good way to make automations respond to your physical presence. There are many times when a cheap NFC tag is by far the best option.

Logging things that don’t happen on a schedule

The problem with running automations on a schedule is that life isn’t always that neat. I have a lot of potted plants in my home, and initially I set up reminders to water them every few days on a schedule. The problem is that this isn’t the best way to keep your plants healthy.

Depending on the conditions, my plants sometimes needed watering sooner than scheduled, and other times they didn’t need watering when the scheduled time came around. I was soon completely out of whack with my scheduled reminders.

NFC tags solved this. I can scan an NFC tag on the bottom of the plant pot to confirm that I’ve watered it, and the timer for the next reminder will start from that point. When I get the notification, if the plant doesn’t need watering yet, I can use the actionable notification to remind me in a day or two. Once I water the plant and scan the tag, the whole process starts again.

Triggering things that motion sensors can’t cover reliably

Motion sensors are great for a lot of automations, but there are plenty of situations where a motion sensor simply isn’t accurate enough. For example, I have drawers for different types of batteries, and I wanted a way to be able to count how many I’ve used so that I know when to buy more.

A motion sensor could tell when I’d opened the drawers, but it couldn’t tell which drawer was opened or how many batteries I’d taken out. With an NFC tag in each drawer, I can scan it, tap the notification that pops up to record how many batteries I’ve used, and my counts always stay accurate.

How to Create Smart Home Automations That Are Personal to You and Your Family

Avoiding false triggers from pets or other movement

Another major problem with motion sensors is that they’re not only triggered by human motion. If you have pets, your motion sensor can’t tell whether it’s you that’s just walked into the room, or your dog. This can really mess your automations up.

Pets are clever, but they’re yet to learn how to use a mobile device to scan an NFC tag. This means that when a tag is scanned, you can be almost certain that it was done by a human and not your cat.

Automations that need to run when you’re sitting still

Getting your bedtime routine to run when you want it to is a challenge. A schedule is no good, because even if you go to bed at exactly the same time every night, you may not want the lights to turn out at exactly the same time if you’re reading or took a little longer to get your pajamas on.

A motion sensor is also no use, since you’re probably fairly still when you’re lying in bed reading or looking at your phone. The best option is to use a physical trigger, and while a smart switch can work well, an NFC tag is also a great choice. You can scan the tag, and your automation will only run when you want it to.

Confirming that you did something

Presence doesn’t equal action

There are plenty of jobs that need doing in my home that my smart home can nag me about, such as putting out the trash. The challenge is knowing when I’ve actually completed them.

For example, my video doorbell can detect that I’ve gone outside the night before the trash collection is due, but it can’t confirm whether I actually put the right bins out. By scanning an NFC tag on the bin, I can be certain that the task has been completed and stop the pestering notifications. I use an NFC tag on the container of my medication for the same purpose, so that my smart home knows when I’ve taken it.

Automations that need to know who triggered them

Build personalized automations

This is one of the biggest benefits of NFC tags, which can make them even more useful than smart buttons for some automations. When you scan an NFC tag, it can pass on the ID of the device that scanned it, allowing you to determine not just if the tag was scanned, but by whom.

For example, if you scan an NFC tag on your washing machine when you start the cycle, the automation can send a notification to the person who scanned the tag when the cycle is completed, rather than everyone in your home.

Limiting automations to specific devices

Another benefit of this feature is that you can set up automations that will only run when specific devices scan an NFC tag. If any other device scans the tag, the automation won’t run.

For example, you could put an NFC tag outside your garage. When you scan the tag, the correct device ID is recognized, and your garage door opener will open the garage. If anyone else tries it, however, the device ID won’t be recognized, and the garage door won’t open.


NFC tags open up even more possibilities

There are plenty of automations that will work perfectly running on a schedule or triggered by a motion sensor. For the cases where these triggers aren’t ideal, an NFC tag can often be a cheap and effective solution.

There aren’t many modern sports cars that manage to feel like a genuine loophole in the system, but this one does. It blends two very different engineering worlds into a single package, and somehow it just works.

It’s quick too, with a 3.9-second sprint to 60 mph and an inline-six that’s already earned a reputation as one of the best in modern performance cars. On top of that, it benefits from one of the widest dealer networks you’ll find outside the domestic brands, which takes a lot of the usual ownership stress out of the equation.

The strange part is how few people seem to have fully clocked what this combination actually means. It feels like one of those setups that won’t be around in this form much longer, even if it probably should be.

In order to give you the most up-to-date and accurate information possible, the data used to compile this article was sourced from BMW, Porsche, and Toyota, as well as other authoritative sources including TopSpeed.

This sports coupe has been around since 2019, but it’s now heading toward the end of the road. When it’s gone, it’ll leave behind one of those weird, unlikely combinations that probably won’t happen again.

It only exists because a few things lined up at exactly the right time, from partnerships to platform sharing. Once that window closes, it’s hard to see it opening again in quite the same way.

The end isn’t coming—it’s already here

In an official statement, the company confirmed production wrapped in March 2026. You can still spec one on the website, but no new cars are coming off the line.

The news didn’t exactly set the auto world on fire, but the impact runs deeper than the headlines suggested. There’s no successor planned, and last time it took two decades for the nameplate to return.

For now, what’s left is a Final Edition model and the slow realization that this chapter is already closed.

A partnership that won’t happen twice

This sports car comes from a platform shared by two automakers that couldn’t be more different if they tried. It wears a Japanese badge, has a German twin, and is built in Graz, Austria.

Without that partnership, it probably never would’ve made it to production in the first place. Now that its German sibling has also bowed out, the deal that made both cars possible has officially run its course.

For this kind of two-door performance car to exist again, the brand would need either a fresh partnership or a completely new platform. The catch is it hasn’t built its own performance inline-six in over 20 years.

Sure, it has the resources to develop one from scratch, but the business case just doesn’t really add up anymore. This sports coupe only happened because the timing and circumstances lined up perfectly — and that window now looks firmly closed.

The Supra’s BMW DNA is exactly what made it work

What started as controversy ended up being its biggest strength

If you still haven’t guessed it, we’re talking about the Toyota GR Supra. When the MkV first dropped, a lot of the JDM crowd wasn’t exactly impressed—the BMW engine swap caused a full-on backlash.

But looking back now that it’s gone, that whole controversy hits differently. What people once saw as a betrayal is actually a big part of what made this car so interesting in the first place.

The B58 came at exactly the right time

Toyota had been working on the next-generation Supra for nearly a decade before the name finally came back in 2019. One of the biggest challenges was figuring out the right engine—something that wouldn’t be shared across the rest of the lineup.

Even with all its R&D resources, building a brand-new inline-six just for the Supra didn’t really make sense financially or practically. It was one of those cases where doing it alone just wasn’t realistic.

By 2019, BMW’s 3.0-liter B58 inline-six had already built a reputation as one of the best performance engines for the money. It stood out for its smoothness, responsiveness, and surprising durability—all traits that lined up perfectly with what Toyota wanted for the Supra.

Timing-wise, it couldn’t have worked out better for Toyota, which saw the engine’s potential right away. In the GR Supra, the B58 puts out 382 horsepower and 368 lb-ft of torque through an eight-speed automatic, good for a 0–60 mph run in about 3.9 seconds, with independent tests dipping closer to 3.7 seconds.

There’s a common misconception that the GR Supra is just a rebadged BMW Z4, but that’s not really the case. The platform underneath both cars was a joint effort from the start, not a one-way handover.

Toyota’s chief engineer, Tetsuya Tada, pushed for a co-developed setup that fit the vision for a modern sports coupe. Drive a Z4 and a Supra back to back and the difference shows pretty quickly—the Supra feels sharper and more performance-focused, while the Z4 leans more into relaxed grand touring.

Beyond all the early controversy, the GR Supra has quietly proven itself as a seriously well-rounded modern sports car. When you strip away the noise, it holds up exactly where it matters most.

It’s quick, easy to live with day to day, and doesn’t come with the usual headaches you’d expect from something this performance-focused. In terms of performance, usability, and long-term ownership confidence, it doesn’t just tick boxes—it actually delivers in all of them.

Performance meets everyday usability

The performance you get from the $59,595 2026 Toyota GR Supra 3.0 is honestly hard to ignore. It’ll do 0–60 mph in about 3.7 to 3.9 seconds straight from the factory, which puts it right in the mix with cars like the $86,600 BMW M4 Competition Coupe.

But the Supra isn’t just about straight-line speed. You’re also getting proper hardware like Michelin Pilot Super Sport tires, adaptive suspension, Brembo brakes, and an active limited-slip diff, all working together to make it feel far more capable than its price suggests.

What’s surprising is how easy it is to live with day to day. There’s usable cargo space, comfortable stock seats, and enough refinement that it doesn’t feel out of place as a daily driver. It can genuinely do track days and the weekday commute without much compromise, which is exactly why it stands out in this segment.

Long-term ownership confidence

The BMW B58 used to be the GR Supra’s biggest talking point for all the wrong reasons, but over time it’s turned into one of its strongest assets. It’s built well beyond its stock output and has a long track record of handling serious tuning without breaking a sweat.

Thanks to its closed-deck design and the durability upgrades over older N5x inline-sixes, it has a lot more headroom than most engines in this class. These days, 600+ horsepower B58 builds are pretty common in the tuning world, but that level of strength and reliability used to be almost unheard of in a setup like this.

The GR Supra gets even more compelling when you factor in Toyota’s massive dealer network — the largest of any non-domestic brand in the U.S. It’s roughly 3.5 times bigger than BMW’s, with Toyota dealerships in just about every major town across all 50 states.

In California alone, Toyota has 136 locations compared with BMW’s 52, which makes servicing and support noticeably easier. That kind of coverage adds real-world convenience that goes beyond just the car itself.

On top of that, the Supra comes with a 5-year/60,000-mile warranty versus the BMW Z4’s 4-year/50,000-mile coverage. That effectively gives you an extra year of protection just for choosing Toyota, which is a pretty solid bonus.

It’s German engineering backed by Japanese peace of mind, and that combination is hard to beat.

A rare performance formula that’s getting harder to find

The GR Supra’s discontinuation isn’t just the end of a model—it feels like the end of an era for this kind of sports car. We’re drifting further away from a market that prioritizes pure performance engineering, and cars like this are becoming harder to justify.

That means a rear-wheel-drive six-cylinder sports coupe at this price point might not come around again for a long time, if ever.

The enthusiast market is slowly disappearing

At $58,300, the 2026 GR Supra 3.0 base trim is definitely not what you’d call cheap. It’s one of Toyota’s more premium and unique offerings, but it still manages to punch above its weight in terms of value.

Compared with its twin, the 2026 BMW Z4 M40i, which starts at $68,400, the Supra comes in noticeably cheaper for basically the same core hardware. Even the 2026 BMW M2 Coupe at $69,000 undercuts it in price but still trails slightly in 0–60 mph performance versus the base Supra.

If you wanted to go Porsche instead, the 718 Cayman unfortunately isn’t part of the picture anymore. Even if it were, you’d be looking at something like a $200,000 718 Cayman GT4 RS to match or beat the Supra’s performance.

The 2026 Toyota GR86 Premium is a great sports car in its own right, but it delivers a very different, more lightweight experience compared to the Supra. At the end of the day, the GR Supra really stood alone as the only car that blended BMW M-level performance with a Toyota price tag.

What comes next won’t be better

It’s hard not to feel a bit pessimistic about where things are heading for driving enthusiasts. As everyday cars keep getting more expensive and priorities shift toward emissions and practicality, traditional sports cars are being pushed further out of reach.

The entry barrier just keeps climbing, and a lot of people who would’ve once been into cars are drifting toward other, more affordable interests instead. If the GR Supra’s successor ends up being a hybrid or EV, it’ll likely feel more filtered, more expensive, and less raw than what came before.

The Supra really nailed a rare formula—BMW-level performance with Toyota reliability—and there’s a real chance we won’t see that combination done quite as well again.
