How to remove accessories from home app

I can’t remove accessories from my home app. I have moved house and they don’t work. I have deleted each accessory, I have deleted the home app, I have no bridge option, I have closed the app, I have restarted my phone. None of the accessories show anywhere on the home app. I have set up a new home in the app and it says I need to delete the accessories. It’s driving me mad. They have all already been deleted
