@Gitspecial It may be because the version of Home Assistant Core is old.

Try changing line 202 of "/config/custom_components/echonetlite/init.py" to the following and restart HA.

    # this api is too recent (around April 2021): hass.config_entries.async_setup_platforms(entry, PLATFORMS)
    await hass.config_entries.async_forward_entry_setups(entry, PLATFORMS)

to

    if hasattr(hass.config_entries, 'async_forward_entry_setups'):
        await hass.config_entries.async_forward_entry_setups(entry, PLATFORMS)
    else:
        # this api is too recent (around April 2021) but keep for backwards compatibility
        hass.config_entries.async_setup_platforms(entry, PLATFORMS)

Thanks, yes it's working after I update the HA.
