 - An additional option for the control of Denon AVR receivers with a built-in web server is using the HTTP interface with `denonavr` platform.
 - The `denonavr` platform supports some additional functionalities like album covers, custom input source names and auto discovery.
 - Marantz receivers seem to a have quite a similar interface. Thus if you own one, give it a try.
+- To remotely power on Marantz receivers with Home Assistant, the Auto-Standby feature must be enabled in the receiver's settings.
 - Sound mode: The command to set a specific sound mode is different from the value of the current sound mode reported by the receiver (sound_mode_raw). There is a key-value structure (sound_mode_dict) that matches the raw sound mode to one of the possible commands to set a sound mode (for instance {'MUSIC':['PLII MUSIC']}. If you get a "Not able to match sound mode" warning, please open an issue on the [denonavr library](https://github.com/scarface-4711/denonavr), stating which raw sound mode could not be matched so it can be added to the matching dictionary. You can find the current raw sound mode under "Development Tools/States" in the front panel.
