Just to preface im a data engineer and can usually figure problems out myself, but the matter documentation with home assistant is really not good and I only found one forum post about this issue. I have some switchbot thermostats connected to a hub mini which is matter enabled. When I want to add the matter integration on my home assistant, it asks me for a URL, the default option ist ws://localhost:5580/ws . If I click submit it says connection failed (obviously). What is this URL? What should be running at that target? Do I need a separate matter server or something? I couldnt find any information about this... How can I set this up? Its not mentioned anywhere on the help page about matter on the home assistant page when I click on the help button.
I have genuinely no idea what I even need to search for since there is no other context, I try to add the matter integration and it asks for this random URL with no explanation of what it should be. I tried just putting the address of the HA server but thatt didnt work either
