I have deleted my HomeKit integration (because the IP changed) and now I can't add it back

Hello, a few days ago, my Ikea hub that connects to my Home Assistant using HomeKit changed its IP. I tried to edit the configuration files trying to assign the new IP, but it was impossible.
So I decided to try to delete it and try to add it again.
However, when I try to add a new device it was not possible. Every time I tried to add a new device, it told me that there are no devices that are not paired but my devices have disappeared completely.
What can I do?

I am still in this situation. Can someone give me some help? Should I open an issue in home assistant repository because this is a bug? What can I do?

Any other channel where I can ask help about this?

I’m in desperate need of help. A lot of my automations depend on this integration, and this has changed from working flawlessly to not work at all without any valid workaround.
Should I open a bug report ? Where else can I ask for help?

You need to unpair your device from HomeKit. Probably the easiest way is to do a factory reset on the device.

And then I will have to repair and rename all my devices ?

Ok, I tried removing from the IKEA app and then adding it back, and it didn’t work.
I guess that a factory reset is my only chance by now. Do you have an idea of how? I can’t find that many docs about it

Sorry no. I didn’t have any IKEA devices. I have other HomeKit devices and know that they need to be unpaired before HA will discover them.
