Installation

HACS

• Add repository "https://github.com/adrigzr/badconga" to custom repositories and select "Integration" category.
• Click on "Install" in the plugin card.

Manual

Copy or link badconga subfolder to config/custom_components.

Configuration

Create a new account on the app and link the device to it.

This integration does not support having the same account in the app and in Home Assistant at the same time. If you try to use the same account as in the app, things will not work correctly as soon as you open the app. Using different accounts in Home Assistant and in the app is supported. Home Assistant will pause controlling the robot and show its state as unknown while the app is in use. Home assistant will resume controlling the robot a few minutes after the app is closed.
