I’m really struggling to get this integration working. The installation documentation looks to be out of date but nonetheless I managed to install the integration up to the point where Home assistant reports that there is a new device discovered.

I click on the Add integration button

and I get the message that the device is already pairing with another controller. This is despite me removing the device from all Homekit pairings (ie in the Home app, in the Neomiser App).

I’ve removed and re-installed the integration multiple times and it’s just impossible to get it working. Anyone have any ideas what I can do?

I managed to resolve this myself. It turns out that the Homekit Code number that looked like an 8 was actually a 0! The error message is misleading and I think it just gives that “Device is already pairing” message as a default, whatever is wrong.

Re-adding the integration, there’s no clear way to delete the exisiting integration so you just have to keep re-adding it until it sticks and re-appears as a new device, brought up the device in the discovered devices list. I entered the correct code and home assistant immediately recognised it. I’ve finally got this added to home assistant after weeks of trying! Hope this helps some others.
