Meross RGB globe.
When trying to adjust the colour temperature on the device/entity control of a meross globe, the following message pop ups :
---"Failed to perform the action light/turn_on. 'LightEntityWrapper' object has no attribute 'min_mireds'"---
While this message pops up on the dash, when a meross globe is targeted in a scene, the globe will not turn on at all regardless of colour/white setting specified in the scene.
A quick google shows the following :
"This error occurs in Home Assistant 2026.3 and later because mired-based color temperature (min_mireds, max_mireds) has been removed in favor of Kelvin (color_temp_kelvin)."
Any help / guidance to resolve this issue would be greatly appreciated.
