New Aqara T2 LED Bulbs Matter Instability

Not sure if I need to open a ticket on GitHub or not, but I have been trying to setup these bulbs with little success.

The bulbs connect to Apple Homef 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 but I can ping the device fine. I do have Unifi network but have everything setup correctly (I think):

I am also having issues. Bought 2, one connected well with HA, the other does not remain connected to Google Home via Streamer or HA.
Both are on the same firmware level. Some units might be faulty.
edit:
I am going to perform a full reset (power cycle 10x), if it doesn’t work I’m exchanging the problematic one.

Update
The first connection to the Thread network over G Streamer was unstable.
The full reset solved the issue by connecting over Matter directly with HA.
Noticed instability due to the device being far from the Thread router (G Streamer). Although the intention was for it to be connected directly with HA.

Sorry I didn’t see this reply. If you group the bulbs in HA via a helper, will they all turn on/off correctly or do some fail to respond?
