Aqara FP2 not updating newly added detection zones to HA via HomeKit

Configuration
1

Hello:
In the process of learning the Aqara FP2 Presence Sensor, I have reworked my zones a couple times. But HA will not update with the new information. I have tried deleting the devices from HomeKit and adding them back but they have the same bad information when loaded back in. I have tried unplugging the sensors to hard boot. I have rebooted Home Assistant.

The Aqara app shows the correct zone information.

HA OS 16.3, core 2025.11.1 running on a dedicated mini computer.
Aqara FP2 firmware up to date. (1.3.3_0002.0099)
Synology Wi-Fi Router

ANY suggestions would be appreciated.

You might need a full purge. If you exhaust all other options, then you can try this -

Delete the integration in HA. Since you’re running HAOS, you’ll need to be able to SSH into it (I use the Advanced SSH add-on with protection mode turned off, but don’t use the ingress! You’ll want to use an app like putty). It’ll be easier to access your registry files if you have the SAMBA add-on setup as well, but you can use SSH for all of it. SSH into your system. BE CAREFUL!!! You can really muck up your system messing with these files. You’ll need to stop core to edit your registry ha core stop. Go into your .storage folder and edit your “core.entity_registry” file (you can do this with cd command to change directory and either nano or vi to edit the file if you’re using SSH). It’s always best practice to backup a copy of a file before editing. Scroll down and you’ll see a list of deleted entities. Purge that list (just the items listed as deleted), again, be careful not to mess up the syntax of the file. Save and exit the file. In SSH, run ha core start to boot core back up. Re-adding the integration now will add it back as if it were the first time you’re adding it, polling for the latest information.

EDIT - Fair warning. Doing this can potentially change (more than likely) the device ID’s of your entities. If you use device ID’s in any of your automations or scripts, it will break them. You’ll need to edit your automations/scripts and update them with the new entities.

How did you succeed to add FP2 to HA ?

Thanks.

@lilp69 IF you are referring to getting them to update the latest changes I made in Aquara app, I have not. If you are asking how did I add them to HA to start, I used HomeKit Device addon.
Sorry for the slow response.
