I’m having some strange behavior when loading the lovelace with gauge, it shows the error for a second and then the normal gauge appears correct, see below:
I have this behaviour too, but additionally other card are also affected:
This is the view, if “custom-gauge” is commented out in ui-lovelace.yaml
And this is the view, if “custom-gauge” is activated in ui-lovelace.yaml
Seems, this is probably the error message, while “custom-gauge” is loading
http://192.168.2.141:8123/static/webcomponents-bundle.js:151:186 TypeError: 'dispatchEvent' called on an object that does not implement interface EventTarget.
EDIT: This behaviour does NOT happen in Chrome, only with Firefox and Edge.
