Chinese smart-home brand SwitchBot has expanded its environmental meter portfolio with two products to provide smarter and more precise environment monitoring.

SwitchBot Meter Pro can display indoor and outdoor temperature and humidity, time, date, and comfort level, alongside weather forecasts when used with a SwitchBot hub. The Meter Pro CO₂ Monitor can precisely monitor the CO₂ status of the house.

Equipped with Swiss-made sensors, they detect indoor temperature and humidity data every four seconds with accuracy within ±0.2˚C and ±2%RH, ensuring accurate and rapid feedback. Meanwhile, based on the indoor temperature and humidity data, the devices can also display the comfort level according to prompts set by users.

With SwitchBot Outdoor Meter, users can access outdoor temperature and humidity data, eliminating the need to step outside. Used with SwitchBot hubs, the devices can access online data to display local temperature, humidity, and weather forecasts for up to 12 hours.

The CO₂ monitor uses non-dispersive infra-red (NDIR) technology to monitor CO₂ levels with precision. It can update CO₂ levels as frequently as every second (every 30 minutes in battery mode and every minute in charging mode by default) with an accuracy of ±50ppm within a range of 400 to 9000ppm, ensuring timely and accurate air quality feedback.

To keep users informed of any significant environmental changes caused by the changes in temperature, humidity or CO₂ levels, both devices offer three types of alerts. Sound alerts emit an up to 100dB alarm with adjustable volume settings of low, medium and high. This can be muted through a physical button or app. Visual alerts flash a number and three different colours on the screen to guide daily activities. And online alerts send app notifications or emails while users are away.

Designed to integrate seamlessly into the SwitchBot ecosystem, these devices can trigger automated actions when environmental data exceed the pre-set limits, such as activating the SwitchBot circulator fan or evaporative humidifier, while used with a SwitchBot hub.

Both devices also support voice control via Alexa, Google Assistant, Siri Shortcuts, IFTTT and SmartThings. Users can monitor and manage settings through an app, including adjusting the content displayed on the screen. Also, SwitchBot Meter Pro is Matter-compatible, enabling integration with various smart home systems when used with SwitchBot Hub 2 or Hub Mini Matter Enabled.

SwitchBot Meter Pro functions for up to 12 months on two AA batteries, while Meter Pro CO₂ Monitor has two power modes – type-C charging and a 12-month battery mode.

For data storage, the Meter Pro supports 68 days of local storage and up to two years of free cloud storage and the CO₂ monitor supports 40 days of local storage and up to two years of free cloud storage. Users can also export data from the app for accurate record-keeping.

Both will be available on the SwitchBot web site (us.switch-bot.com/products/switchbot-meter-pro) and Amazon stores this month.
