Recently bought a new dishwasher and being a Home Assistant nerd that I am, I opted for a “connected” one. Siemens unit with Home Connect. Did some quick online searches, noticed there was a Home Assistant integration for it so there we go!

Fast forward now that the unit is installed and I finally have time to fool around with the “smart” features, I tried to configure the integration in HA. However, Home Connect is a completely busted platform!

Aside from many “captcha validation errors” (not on a VPN, just regular me behind a computer), I can’t register an application in the Home Connect Developer platform.

The freakin’ platform does not allow me to set an OAuth redirect URL! It keeps giving me the error “The character / is not allowed.” (I dont know how to add screenshots to this post).

Setting the required redirect URI won’t work: “”

Fun fact: this is the hint text under the field: "Please provide a valid redirect URI for the OAuth process, e.g. "

Even entering throws the “The character / is not allowed” error.

How to proceed?
