How to buy smart plugs for less

Smart plugs are sold as singles and multi-packs of the same model, so the sticker price tells you almost nothing. Cost per plug is the comparison — and the bulk saving here is real but modest, usually 5-10%, not the halving the "2 PACK" framing suggests.

  • Divide by the pack count before comparing models. Across what we track, the same Z-Wave plug runs about $26 as a single and $23.80 each in a two-pack — worth taking if you need two, not worth buying a spare for.
  • Pay for energy monitoring only if you will read it. Metering versions cost a couple of dollars more per plug; without a dashboard you actually check, that is a feature you own but never use.
  • Match the radio to the hub you already have. A Z-Wave plug is useless without a Z-Wave hub, and a cheaper Wi-Fi plug is not a substitute if your automations live on Z-Wave — compare within the protocol you run.
  • Indoor vs outdoor is a weatherproofing rating, not a marketing tier. An outdoor-rated plug costs more per plug for a reason; buying the indoor one for a porch is how you replace it twice.

How we rank smart plugs

We take each listing’s last-seen price and divide it by the plug — the unit that actually matters here — so a big pack and a small one line up on the same scale. The cheapest per plug wins, not the biggest label or the lowest sticker price.

What we check

Cheapest isn’t always best value. For smart plugs we surface the trust signal that separates the real thing from filler: $/plug, not $/box.
