Zb1 only allowing 2 sets together

On the zb1 I can only string 2 sets of lights together.  Why?

Hi there,

Thanks for your question.
The power adapter included with the kit is 12V and 1.25A, which is designed to support a maximum of 2 strings of ZB1 lights. Our app is also limited to recognizing only 2 strings.
If you connect more than 2 strings, the additional ones may not be recognized by the app, and you may experience insufficient voltage, resulting in dim lights, color inconsistencies, or flickering.
Feel free to reach out if you have any questions.

Best regards,
