Home Assistant integration for Casambi using Bluetooth

This is a Home Assistant integration for Casambi networks using Bluetooth. Since this is an unofficial implementation of the rather complex undocumented protocol used by the Casambi app there may be issues in networks configured differently to the one used to test this integration. Please see the information below on how to report such issues.

A more mature HA integration for Casambi networks can be found under https://github.com/hellqvio86/home_assistant_casambi. This integration requires a network gateway to always connect the network to the Casambi cloud.

Network configuration

See https://github.com/lkempf/casambi-bt#casambi-network-setup for the proper network configuration. If you get "Unexcpected error" or "Failed to connect" different network configurations are the most common cause. Due to the high complexity of the protocol I won't be able to support all configurations allthough I might try if the suggested config doesn't work and the fix isn't to complex.

Installation

Manual

Place the casambi_bt folder in the custom_components folder.

HACS

Reporting issues

Before reporting issues make sure that you have the debug log enabled for all relevant components. This can be done by placing the following in configuration.yaml of your HA installation:

logger:
  default: info
  logs:
    CasambiBt: debug
    custom_components.casambi_bt: debug

The log might contain sensitive information about the network (including your network password and the email address used for the network) so sanitize it first or mail it to the address on my github profile referencing your issue.

Development

When developing you might also want to change https://github.com/lkempf/casambi-bt. To make this more convenient run

pip install -e PATH_TO_CASAMBI_BT_REPO

in the homeassistant venv and then start HA with

hass -c config --skip-pip-packages casambi-bt

If you are unsure what these terms mean you might want to have a look at https://developers.home-assistant.io/docs/development_environment first.
