it seems that i cannot find the proper information on how to read entity details. For example, i have a Yamaha AVR. It has the input selectors for HDMI and Audio only. I want to check the input selection so that the cinema mode of my lights only start on input=HDMI. The component reads the current input, as long as i see it in the HASS startup messages, but i don’t know how to access them in automation scripts. The dev-state page isn’t very verbose, either.
Is there a reason why i cannot see any other attributes than the supported_features in the dev-state list, although they should be known to Home Assistant?
