What the differences mean

Screen size

The SwitchBot Meter Plus has a 3 inch LCD and the SwitchBot Meter a 2.1 inch one. Both are always on, monochrome and readable without the app, but the larger digits are the practical reason to choose the Plus for a shelf or wall across a room.

Body shape

The SwitchBot Meter is a compact 55 x 55 x 24 mm square at 69 g. The SwitchBot Meter Plus measures 79 x 64.5 x 21.6 mm, wider and thinner, at 64 g. Both stand or stick on easily, so weight is not a factor.

Sensing, battery and hub needs

No difference to plan around: both measure temperature and humidity, both run on 2 AAA cells for about a year, and both need a SwitchBot Hub for Wi-Fi, alerts and Matter. You do not get better sensing by paying for the Plus.

Smart home platforms

Both list Google Home, Alexa, Apple Home, SmartThings and Home Assistant, with Matter through the hub. The SwitchBot Meter Plus does not open any platform the SwitchBot Meter lacks.

Age of the design

The SwitchBot Meter dates from 2019 and the SwitchBot Meter Plus from 2022. Their spec sheets are otherwise close, so the newer year buys the screen and little else.

Which one to buy if

  • you want a sensor in every room without overspending
    SwitchBot Meter

    The SwitchBot Meter does the same sensing and hub-based smart home job as the Plus at a lower price.

  • you need to read the numbers from across the room
    SwitchBot Meter Plus

    The SwitchBot Meter Plus has a 3 inch LCD against 2.1 inches, so the digits are much easier to read from a distance.

  • the sensor goes in a nursery, wine fridge or shelf where you check it by eye
    SwitchBot Meter Plus

    The larger display of the SwitchBot Meter Plus makes a quick glance more reliable.

  • you will read everything in the SwitchBot app or through a hub

    When the screen is rarely looked at, the extra display of the Plus buys nothing and the SwitchBot Meter is enough.

What owners say

Owners of both SwitchBot models say the same things first: quick Bluetooth setup, an always-on LCD readable without the app, and units bought in bulk that agree with each other to within a fraction of a degree. Both groups also learn the same lesson about the SwitchBot Hub, since Wi-Fi, alerts and Matter all wait for it. SwitchBot Meter owners add that a set of AAA cells lasts a long stretch, that humidity reads slightly less precise than temperature and that a minority saw display or longevity problems, with support sending replacements quickly. SwitchBot Meter Plus owners single out the larger display and fast update, and some found it matched a calibrated reference thermometer, but a minority report the offset drifting after months until reset and a few describe early quality problems on individual units.

Upgrading from the SwitchBot Meter?

Moving up from the SwitchBot Meter to the SwitchBot Meter Plus changes the display and almost nothing else. Both have the same sensors, the same battery rating, the same Bluetooth-only base and the same need for a SwitchBot Hub, and both list the same smart home platforms. The gain is a 3 inch screen in place of a 2.1 inch one. If your SwitchBot Meter already gives you readings you can see, there is no reason to replace it. If you keep squinting at it from across a room, the Plus is the upgrade to make.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
