Connect BOOKOO Themis Mini or Ultra to Brew Better

Brew Better supports BOOKOO Themis Mini and Themis Ultra scales on iOS and Android. Connect your scale from Brew Better’s Bluetooth page, not in your device’s Bluetooth settings. This guide covers setup and what to check if your scale does not appear. If you are still choosing a brewing app, read our BOOKOO app alternative guide first.

Download on the App Store or Get it on Google Play before following the steps below.

Before You Connect

Before connecting your BOOKOO scale, make sure:

1. Bluetooth is enabled on your device — Open your phone or tablet’s settings and turn on Bluetooth.
2. Your BOOKOO scale is powered on — Press the power button and wait for the display to show the weight reading.
3. The scale is not connected to another app — A Bluetooth scale can only talk to one app at a time. Close the official BOOKOO app if it is still connected.
4. Brew Better is open — Launch the Brew Better app on your phone or tablet.

Note: You do not need to pair your BOOKOO scale in your device’s Bluetooth settings. Brew Better connects directly to the scale.

How to Connect Your BOOKOO Scale

There are two ways to connect your BOOKOO scale in Brew Better:

Method 1: Via the Bluetooth Banner

On the home screen, you’ll see a Bluetooth status banner at the top. Tap it to enter the Bluetooth connection page. The app will automatically start scanning for nearby scales. When your BOOKOO scale appears in the list, tap it to connect.

Method 2: Via the Brew Button

Tap the brew button at the bottom of the home screen to start a new brew. If no scale is connected, the app will prompt you to connect one. You’ll be taken to the Bluetooth page where scanning begins automatically.

If Your BOOKOO Scale Doesn’t Appear

If scanning completes without finding your BOOKOO Themis Mini or Themis Ultra:

1. Check that Bluetooth is on. On iOS, grant Brew Better Bluetooth permission; on Android, grant Nearby devices permission when prompted. Older Android versions may request location permission for BLE scanning.
2. Keep the scale powered on and close to your phone or tablet.
3. Disconnect any other app or device that is connected to the scale.
4. Tap Start Scanning at the bottom of Brew Better’s Bluetooth page to scan again.

For model-specific Bluetooth settings, use BOOKOO’s official support. Keep BOOKOO’s official app for firmware updates and device settings.

Tare and Timer from the App

Once connected, you don’t have to reach for the scale. Brew Better can tare your BOOKOO scale and start, stop, and reset its timer directly from your phone, and it reads the scale’s battery level so you know when it needs charging.

Start Brewing

With your BOOKOO scale connected, you’re ready to brew. Place your dripper and server on the scale, then start pouring. Brew Better will automatically detect the brew and begin recording your flow rate curve in real-time.
