SwitchBot Meter Pro Review: Temperature, Humidity and Matter Integration

The SwitchBot Meter Pro is the temperature and humidity version of the Meter Pro CO₂. The Amazon listing linked here is the CO₂ model, which shares the screen, alerts and hub integration. This review explains what the plain Meter Pro offers, what the CO₂ model adds, and which to buy.

Verdict

The Meter Pro is SwitchBot’s large-display thermometer and hygrometer: temperature, humidity, time, date and a comfort indicator on a screen you can read from across the room. It connects to the SwitchBot app over Bluetooth nearby, and through a SwitchBot hub it gains cloud alerts, history and Matter integration for Apple Home, Google Home and other platforms. The Amazon listing linked from this review is the Meter Pro CO₂, which adds an NDIR CO₂ sensor to the same design. If you need CO₂, buy that one; if you want a comfort monitor that doubles as a clock and can drive a humidifier or heater through a hub, the plain Meter Pro is the lower-cost route.

What Is Different From the Meter Pro CO₂

Item Meter Pro Meter Pro CO₂ (Amazon listing)
Temperature and humidity Yes Yes
CO₂ No Yes, Swiss-made NDIR, ±50 ppm, 400 to 9000 ppm
Clock, date, comfort indicator Yes Yes
Alerts Screen and app (hub for remote) Sound, screen and app (hub for remote)
Hub-based cloud and Matter Yes Yes
Battery Long life on batteries per SwitchBot Up to 12 months per the listing

The CO₂ column is taken from the Amazon listing. The Meter Pro column reflects SwitchBot’s product descriptions; where we could not confirm a figure we have described it qualitatively.

Temperature and Humidity

SwitchBot’s meters use a digital temperature and humidity sensor of the type found in most consumer monitors, typically good to within a few percent RH and a fraction of a degree. That is enough to decide whether a nursery is too dry in winter, whether a basement is in the mould-risk range, or whether a wine store is stable. The large screen is the point: a small hygrometer gives the same numbers, but you have to walk up to it. For checking a unit like this against a reference, see how to calibrate a hygrometer and how to measure relative humidity correctly.

The Hub, Matter and Automation

On its own the Meter Pro is a Bluetooth device: the SwitchBot app reads it when the phone is nearby and stores recent history. A SwitchBot hub bridges it to the cloud, which enables notifications anywhere, longer history and export, and exposure to Matter so the readings appear in Apple Home or Google Home. From there the automations follow: humidity above a threshold switches on a dehumidifier through a smart plug; temperature below a threshold nudges a heater. Households already invested in SwitchBot curtains, plugs and bots get the most from this. Anyone else should price in the hub. The reasoning about hub-based versus built-in Wi-Fi designs is in Bluetooth versus Wi-Fi monitors.

Display and Placement

The clock-style screen suits a bedside table, a kitchen wall or a classroom. Place it at the height people live at, away from windows, radiators and direct sun, and allow it time to settle after moving it. The comfort indicator is derived from both readings and is a quick way to tell a visitor or a child whether the room is fine without explaining the numbers. Owners often pair one in a bedroom with one in a basement or nursery, since the app shows every meter on the account together. Guidance on where comfort monitors read reliably is in choosing a humidity meter for indoor use.

Strengths

  • Large, readable display with clock and comfort indicator.
  • Matter and cloud integration through a hub.
  • Long battery life and simple setup.
  • Lower price than the CO₂ model for households that only need comfort readings.

Limitations

  • No CO₂, so it cannot answer ventilation questions.
  • Remote alerts and Matter require a SwitchBot hub.
  • The Amazon listing linked here is the CO₂ sibling; check the model before ordering.

How It Compares

The Meter Pro CO₂ is the same device with an NDIR sensor. The Qingping Temp & RH Monitor T is an e-ink Thread sensor for Apple Home with a much longer battery but no large display. The Qingping CO₂ monitor has Wi-Fi built in and needs no hub.

How We Research

This review is based on SwitchBot’s published product documentation for the Meter Pro family, the Amazon listing for the Meter Pro CO₂ and owner reports. We did not run laboratory tests.

Frequently Asked Questions

Is the Amazon listing the Meter Pro?

The listing linked here is the Meter Pro CO₂, the sibling with an NDIR CO₂ sensor. The plain Meter Pro shares the display style, alerts and hub integration but measures temperature and humidity only.

Does the Meter Pro support Matter?

Through a compatible SwitchBot hub, SwitchBot exposes its meters to Matter so they appear in Apple Home, Google Home and other Matter platforms. Without a hub it is a Bluetooth device.

What is the comfort indicator?

An on-screen summary derived from temperature and humidity that shows whether the room is in a comfortable range, similar to the indicator on the CO₂ model.

Should I buy the Meter Pro or the Meter Pro CO₂?

If ventilation is a question you want answered, the CO₂ model. If you only need comfort readings and a clock, the plain Meter Pro costs less and does the same job for those two measurements.
