Yamaha Receiver Binding: NumberFormatException for channel input <TUNER>

Add-ons Bindings

Hi guys,

I recently started implementing and configuring the yamaha binding to use my receiver as well for home automation, e.g. switch the plug for the record player if the input PHONO is set.

Anyway, I ran into one issue according to the returning messages.

If I use the channel TUNER, I am able to produce the following exception:
java.lang.NumberFormatException: For input string: “o Preset”

The log messages (with binding trace enabled) according to this exception shows the following:

2021-10-28 16:41:15.372 [DEBUG] [.internal.protocol.xml.XMLConnection] - Making POST to http://xxx.xxx.xxx.xxx:80/YamahaRemoteControl/ctrl with payload: <?xml version="1.0" encoding="utf-8"?><YAMAHA_AV cmd="GET"><Tuner><Play_Control><Preset><Preset_Sel_Item>GetParam</Preset_Sel_Item></Preset></Play_Control></Tuner></YAMAHA_AV>

Getting the TUNER params means that the Yamaha Receiver responds with the preset list of programmed stations.
In my case, the Yamaha Receiver (RX-A1030) returns the following (sniffed with Wireshark):

<Tuner>
	<Play_Control>
		<Preset>
			<Preset_Sel_Item>
				<Item_1>
					<Param>No Preset</Param>
					<RW>R</RW>
					<Title></Title>
				</Item_1>
				<Item_2>
					<Param>1</Param>
					<RW>RW</RW>
					<Title>1 : FM 90.10 MHz</Title>
				</Item_2>
			</Preset_Sel_Item>
		</Preset>
	</Play_Control>
</Tuner>

Within this response, we can see that <Item_1> has the “No Preset”, which is obviously not handled by the Yamaha Receiver Binding yet.

Currently, I have no idea how to solve this issue other than to just report this correlation/bug.

I am hoping, this will help to understand the issue and solve it in coming releases. :slight_smile:

Best regards

Good morning Wolfgang,

ah yes, you’re right.
It’s definitely the same issue! I didn’t find such a topic while searching yesterday.
Thank you for keeping it together, I also noted, that the openhab-bot linked my post there.

Best regards
Stephan
