Do you also know the question of your guests for the wifi-key? I found a litte but nice solution for sharing access to the guest-wifi of my fritzbox.
After configuring the guest-wifi at the fritz!os i just took a screenshot of the qr-code that includes the accessdata and saved it to the html-folder of openhab.
Then i just added the following lines into my sitemap:
Hello @e36Alex
is there an option to get the source url of the WLAN QR code picture? I checked the element it with dev tools of my browser, but I did not get any url.
Hello,
I know where to store the data localy
I mean if you know, where the location of the qr code on the fitzbox is. The data folder on the filesystem on the fritzbox. At this time I use a picture of the qr code saved on the filesystem of my raspberry. I would rather use the linked picture as destination target of the qr code.
