[MainUI] missing channel icons

[marcelrv]

The problem

Channel icons are missing in most pages

In the item link page it is working well

but most other places the icon (category) is lost

Expected behavior

If the channel icon is available, I would expect to see it, similar as it is showing for the channel in the channel page.

Maybe due to a bad category set by the binding?
openhab/openhab-addons#9335
What is the binding? Mihome?

[marcelrv]

It is from the miio binding.
But I would be surprised that would be the issue as I'm the channel page it does pick up the right icons, and the items created from the channels get a working icon. ( Note the items you see in the screenshot are are auto created from the channel without further editing)

I had a quick look at the binding and the brightness channel is defined as a Number type (in the commonChannels.xml file) and is being sent Dimmer/Setpoint commands ??? Perhaps it should be a Dimmer type and not Number?

Also the binding has lots of Number channels that have options defined which I was told not to do that when I had a binding get reviewed that did that. The channels should be String type if they have options not Number.

I suggest you raise this as an Addon issue to be looked at as I do not use the binding and am not an expert but it appears to be something that needs looking at.

For miio, I found that:

@lolodomo yes I found during testing yesterday that indeed dimmablelight is deprecated.
PR to fix that is in progress.
The icon in the screenshot is light to though, but a dimmablelight.

@Skinah the example in the screen is from
https://github.com/openhab/openhab-addons/blob/645032db5f47f91a1bb66de28930dfee3386b20e/bundles/org.openhab.binding.miio/src/main/resources/database/yeelink.light.lamp1.json#L60
The role is indeed dimmer.
The channels are dynamically generated from the JSON file, not using the XML channel config. (To be precise: depending the JSON file)

Where do you see documentaries that all channels with options need to be string? That is not my experience. The XML needs to have a string in the definition, but the channel can be numeric is my experience.

The component that displays link details doesn't have the category info because it's defined by the channel type and all it has it the channel.

openhab-webui/bundles/org.openhab.ui/web/src/components/model/link-details.vue

Line 11 in 9ea63a0

<span slot="media" class="item-initial">{{l.channel.label ? l.channel.label[0] : '?'}}</span>

Not sure I care about this enough to fix it.
