There are a number of other characteristics available, but their functions have not yet been determined.

The JSON and YAML will need to have all occurrences of "D8:28:C9:xx:xx:xx" replaced with your OPAL MAC address and replace each { ... } with the relevant information pertaining to your setup.

YAML is updated to be compatible with 2022.12+ Releases of Home Assistant.
