Connect batteries to the NDS Energy app.

The Dometic Büttner Tempra TLB150 batteries currently installed can be connected via Bluetooth to the “NDS Energy” smartphone app. Here are instructions on how to add the batteries to the app:

1. Download the app and log in

First, download the “NDS Energy” app from the App Store or Google Play Store. Then log in if you already have an account; otherwise, create one. Registration requires your name and email address. When creating your account, be sure to accept the privacy policy. 

2. Connect batteries

After logging in or registering, a window will automatically open displaying all nearby Bluetooth devices. To connect the batteries, turn on the battery using the button (1). If the batteries are already on, turn them off and then back on again. To turn them off, press and hold the button for eight seconds; to turn them back on, press the button again.

The battery can now be connected to the app within five minutes. If this time is exceeded, the process must be repeated.

Note: DIP switches 5 and 6 on the battery (2) must be set to ON.

The battery should now appear in the NDS Energy app. The battery's Bluetooth name consists of the model (A) and the serial number (B); in this case, the battery is displayed as “TLB1502601599” or “KAA_2601599_TLB150”.

3. Find batteries

If the list of Bluetooth devices does not open automatically in the app, follow these steps:

Open the menu in the app (top right) and select Bluetooth. Then click “Scan for devices” and select the battery you are looking for.

If there are multiple auxiliary batteries in the vehicle, they will be automatically added to the app by connecting to the master battery.

4. See information

You can then view all the information about the batteries in the app.

You can manage the batteries and disconnect them if necessary via the Bluetooth menu.
