Describe the bug

HomeAssistant is generating the warning:

[homeassistant.components.light] light.office_plate_1_light_12 (<class 'custom_components.openhasp.light.HASPLight'>) does not report a color mode, this will stop working in Home Assistant Core 2025.3, please create a bug report at https://github.com/HASwitchPlate/openHASP-custom-component/issues

I believe this is the related notice on the change: https://developers.home-assistant.io/blog/2024/02/12/light-color-mode-mandatory

this will stop working in Home Assistant Core 2025.3

What is your version of Home Assistant please?

If anyone is still having issues with this i found that changing the following code at line 109 in light.py fixes the problem.

from
_attr_supported_color_modes = {ColorMode.BRIGHTNESS}
to
_attr_color_mode = ColorMode.ONOFF
_attr_supported_color_modes = {ColorMode.ONOFF}

from _attr_supported_color_modes = {ColorMode.BRIGHTNESS} to _attr_color_mode = ColorMode.ONOFF _attr_supported_color_modes = {ColorMode.ONOFF}

this seems logical, to change to a toggle, however i think also could be changed to just add _attr_supported_color_modes = {ColorMode.BRIGHTNESS}, would you raise a PR?
