You’re trying to display an image inside the oh-button component I suppose. oh-button (and the f7-component it’s based on) doesn’t support slots - so this will not work.
Generally the oh-button component only supports icons from the f7- and the material-iconset, which I attached an example below.
For explanation to the oh-image component you’re trying to use - the ‘/static/’ path corresponds with the ‘/etc/openhab/html/’ folder of your installation. And you don’t need the equal sign in that case, because you’re not accessing a prop, item or variable. So this would work, if you place an image in the above mentioned path:
- component: oh-image
config:
url: "/static/a1.png"
To reach your initial goal, you have to use a small workaround. (see the third button example in the code below) Be aware that there is a slight distinction with this workaround in the ‘hover’ and ‘pressed’-state of the button.
You also can leave your icon inside the ‘/etc/openhab/icons/classic/’ folder then, as ‘oh-icon’ is looking for icons there and in the integrated OH-iconset.
