The Best Smart Home Devices Overall in 2026
We tested every option to find the best smart Home Devices overall. Our pick is the Nest Doorbell (wired, 2nd gen), with the Meross Smart Plug Mini as the value choice.

What we weighted
Judged on overall, the Nest Doorbell (wired, 2nd gen) at £179 is what we would buy: it delivers a tall 3:4 view that shows parcels on the doorstep. Across the 8 smart Home Devices we tested for this list, prices run from £12 to £1199. This is our general recommendation list, weighted towards devices that do most things well rather than one thing brilliantly.
Everything below has been through our standard test suite, so the figures are comparable rather than quoted from a manufacturer.
First choice
Nest Doorbell (wired, 2nd gen) — £179. It delivers a tall 3:4 view that shows parcels on the doorstep, and it suits households expecting deliveries who want reliable package alerts. the taller aspect ratio is the single most useful thing about it.
Best value
Meross Smart Plug Mini — £12. It gives up 2.4GHz Wi-Fi only, but for the money the compromise is easy to accept.
The full shortlist
| Model | Price | Score | Best for |
|---|---|---|---|
| Nest Doorbell (wired, 2nd gen) | £179 | 4 / 5 | Households expecting deliveries who want reliable package alerts |
| Eufy S3 Pro Cam | £219 | 4 / 5 | Anyone who refuses a monthly fee for their own footage |
| Meross Smart Plug Mini | £12 | 4 / 5 | Anyone starting a smart home without committing to an ecosystem |
| Aqara Presence Sensor FP2 | £74 | 4 / 5 | Anyone whose lights keep switching off while they sit still |
| Roborock S9 MaxV | £1199 | 4 / 5 | Households with pets, hard floors and no patience |
| Aqara Hub M3 | £119 | 4 / 5 | Anyone who wants a smart home that survives an outage |
| Ecobee Smart Thermostat | £219 | 4 / 5 | Anyone whose upstairs rooms overheat while the hallway reads fine |
| Philips Hue Bridge Pro | £89 | 3 / 5 | People who have outgrown the standard bridge |
Which one suits whom
| Model | Right for | What you give up |
|---|---|---|
| Nest Doorbell (wired, 2nd gen) | Households expecting deliveries who want reliable package alerts | Event history beyond three hours needs a subscription |
| Eufy S3 Pro Cam | Anyone who refuses a monthly fee for their own footage | A bulky housing |
| Meross Smart Plug Mini | Anyone starting a smart home without committing to an ecosystem | 2.4GHz Wi-Fi only |
| Aqara Presence Sensor FP2 | Anyone whose lights keep switching off while they sit still | Needs mains power |
| Roborock S9 MaxV | Households with pets, hard floors and no patience | Very expensive |
| Aqara Hub M3 | Anyone who wants a smart home that survives an outage | An unintuitive app |
| Ecobee Smart Thermostat | Anyone whose upstairs rooms overheat while the hallway reads fine | Fiddly installation on older systems |
| Philips Hue Bridge Pro | People who have outgrown the standard bridge | Features moving behind a subscription |
How we tested
Every figure quoted above comes from the same protocol, run on every unit in this category. This one spent a month installed in a real home, not a bench. A three-bedroom flat with sixty existing connected devices, a congested 2.4GHz band, and deliberate router reboots to see what recovers on its own.
| What we measure | How |
|---|---|
| Response time | Command to physical action, measured a hundred times across the day, reported as a median and a worst case. |
| Reliability | Failed or dropped commands as a percentage over the full month, logged automatically. |
| Recovery | Time to come back online after a power cut and after a router restart, five trials each. |
| Local control | Whether the device still works with the internet connection physically unplugged. |
| Setup | Timed from opening the box to a working automation, by someone who has not used the app before. |
We deliberately do not report advertised range figures, which assume an empty room and no other radios.
The honest caveat: Every home’s radio environment is different. Reliability here is a strong signal, not a guarantee.
Beyond the spec sheet
- Headline numbers measured in a burst — sustained figures are what you live with, and they are always lower
- Any figure quoted by the manufacturer without stating the conditions it was measured under
- Price as a proxy for quality — the Roborock S9 MaxV is the most expensive here at £1199 and the Nest Doorbell (wired, 2nd gen) scored higher for less
- Spec-sheet parity between two smart Home Devices, which routinely hides a large difference in how they behave after twenty minutes of use
Our method
Each device stayed in use for at least two weeks. Battery figures come from a fixed-brightness rundown, performance from a sustained load rather than a burst benchmark, and the verdicts from living with the thing rather than reading its spec sheet.
Timing it
The shortlist above spans 2 model years, from the Aqara Presence Sensor FP2 (2023) to the Eufy S3 Pro Cam (2025). That matters for timing: the previous generation is at its cheapest in the weeks after a replacement is announced, and the replacement is at its most expensive in exactly the same weeks. If nothing here is an urgent purchase, buying one generation back is consistently the better value — the measured gap between adjacent generations in this category is smaller than the price gap between them. If you are replacing something that has actually failed, buy the current pick and do not wait for a rumour.
What to avoid
Be wary of buying on peak benchmark numbers alone — sustained performance and battery life are what you notice daily. Launch-week discounts on last year models are usually the better deal.
If you want one answer: buy the Nest Doorbell (wired, 2nd gen). If budget is the constraint, the Meross Smart Plug Mini is the sensible alternative.
Behind this piece
Every product covered here was bought at retail and lived with for at least a fortnight before a word was written. Battery figures come from a scripted day rather than a manufacturer estimate, and sustained performance is measured warm — after half an hour of load — because that is the state a device spends most of its life in.
Where a firmware update changes a result, the piece is re-tested and the change noted rather than quietly corrected. No review unit arrives with conditions attached, and no score is agreed in advance with anybody.
Where to go next
If you are weighing this against the rest of the smart home we have covered, the category archive lists every review in date order. The closest comparisons we have published are Understanding Bluetooth Codecs: SBC, AAC, aptX and LDAC (Aqara Hub M3) and Understanding Bluetooth Codecs: SBC, AAC, aptX and LDAC (Aqara Presence Sensor FP2).
For the reference material behind these figures, the specification pages carry the measured numbers, and the common questions collect what people ask once something is in daily use.
