Both Wi-Fi and Bluetooth are under the category of wireless technology. SwitchBot Meter uses Bluetooth, but a Wi-Fi option can be easily added.

The SwitchBot Meter uses the Bluetooth Low Energy protocol (BLE) to communicate. So on its own, the Meter is limited to Bluetooth range (e.g. around the house - like a Bluetooth speaker).

If we want to monitor SwitchBot Meters remotely (e.g. away from the house), we need to use them in conjunction with a SwitchBot Hub (Plus), which relays the data of any in-range SwitchBot Meter to the internet using our local Wi-Fi network.

Yes. Multiple SwitchBot Meters can be used on the same SwitchBot App, with the same account logged in.

You'll find 2 AAA batteries inside Meter/MeterPlus, which can be used for approximately 1 year (Panasonic batteries are recommended). While Meter/Meter Plus can measure temperatures down to -20°C, it is recommended that Meter/Meter Plus be used at temperatures between -10°C and 60°C, as the life of your device may be shortened if used in extreme environments. Depending on the temperature and the frequency of data readings, service life may also be shortened.

It all depends on whether or not you need to monitor your Meter remotely and/or if you want to back up or sync your data with others on the SwitchBot cloud.

To use the SwitchBot Meter alone? You can either check the readings from the LED screen directly, just like the traditional thermometer and hygrometer.

Alternatively, you can use the SwitchBot App to pair your mobile phone with the Meter. This unlocks more possibilities like getting the last 36 days of historical data (via Bluetooth), getting alert notifications, calibrating the Meter, etc.

The Meters use BLE to communicate, so on their own, they are limited to Bluetooth range (e.g. around the house - like a Bluetooth speaker).
