Aqara T2 and Nanoleaf LED Bulbs Matter Instability

[DamoclesSword]

The problem

I have tried other support avenues, including contacting Aqara/Nanoleaf, but to no avail.

I have been trying to setup these bulbs with little success.

The Aqara bulbs connect to Apple Homekit fine, but when enabling pairing mode, the bulbs may or may not connect to Home Assistant. I have a strong Wi-Fi network and 3 Apple HomePod mini acting as border routers. Some bulbs take 5-10 tries to connect to HA

Out of my 5 bulbs:

2 connected to HA first, then were shared to Homekit,
2 connected to Homekit then were shared to HA (because they wouldnt connect to HA first)
1 connected to Homekit but wont share to HA at all.

In HA, the two I connected natively are connected fine but the two I shared keep becoming unavailable.

I also grouped them all via a helper, but when doing a group command only a couple bulbs respond. All bulbs respond well in Homekit though.

Looking at the logs, I get errors like I posted below, but even when the device is unavailable, I can ping the device fine.

I do have Unifi network but have everything setup correctly (I think).

For Nanoleaf, the bulbs are constantly losing their thread connection despite what I believe to be a strong thread network. I also have several ESP BLE Proxy devices setup throughout my home.

Here is one of the logs for Aqara:
