KeyError when connecting to bridge

[chris-downs]

I'm getting the following on startup after I connect to the bridge:

(luminance:5441): Gtk-WARNING **: Theme parsing error: gtk.css:68:35: The style property GtkButton:child-displacement-x is deprecated and shouldn't be used anymore. It will be removed in a future version

During handling of the above exception, another exception occurred:

It looks like this occurs when a White-only light is encountered, as they don't have a 'hue' parameter.

Here is the state object for the white-only light that it's bombing out on:

{'uniqueid': '00:17:88:01:02:30:1c:2c-0b', 'state': {'alert': 'none', 'on': True, 'reachable': True, 'bri': 254}, 'type': 'Dimmable light', 'modelid': 'LWB006', 'manufacturername': 'Philips', 'swversion': '5.38.2.19136', 'name': 'Bedroom Nightstand'}

It doesn't have a key named "hue"

[chris-downs]

I was able to work around it by forcing the color chooser to white if it encounters a light that throws a KeyError when the hue or saturation params are missing:

entity.py:59

        if self.model.on:
            try:
                self.color_chooser.set_rgba(
                    hsv_to_gdk_rgb(
                        self.model.hue,
                        self.model.saturation,
                        self.model.brightness
                    )
                )
            except KeyError:
                self.color_chooser.set_rgba(
                    hsv_to_gdk_rgb(
                        0,
                        0,
                        self.model.brightness
                    )
                )

I can submit a PR but it's kind of a hacky approach and you might want to fix it a different way\add support for non-color lights. I'll leave it up to you!

Same problem with Hue White Ambiance bulbs as well.

Also came across this and only have Hue White Ambiance bulbs on my network.

[jay-to-the-dee]

Have tried your patch @chris-downs :) it helps and gets the GUI running at least for it bit, but it ends up crashing after a few changes of settings.

Minimal workaround for also setup with smart plugs that are supported by hue bridge and Philips' app is:

Note that phue has a new release, please see https://pypi.org/project/phue/#history

I think I have color lights (am able to change color from iPhone) and I get this crash as well, so perhaps not specifically related to only non-color ones?

Similar error occurs to me when connecting to the bridge:
