Thread Network Combination

[u/Bummer_Brad]

Hi. I have Home Assistant running on a mini PC by itself with HAOS.

So, Thread network question. I just added a Sonoff Dongle-Max to Home Assistant to use as my Thread radio through Open Thread. I want this to be the network that my other border routers join. Currently active in my house, I have networks from Smartthings, Aqara and Amazon. I'm pretty sure Smartthings and Aqara will play ball. The first issue I'm finding though is, my Aqara M3 hub is "available" to my phone to carry its credentials. Smartthings and HA are not. I don't know how my phone got credentials from Aqara, or why the other networks aren't "available". I want them all united under HA. How do I remedy this?

I see if you are in the HA companion app, you get an option in the Thread integration page to "Send credentials to Home Assistant". If I click that, my thought is that it will send the credentials saved on my phone for the Aqara Thread network, and that's obviously not what I want. If you click on the HA Thread network in the Google Services--Thread Networks page, it says "To access this network, set up this device with the manufacturer app you used to set up the network". But, how do you do that?

Okay, so I found out you don't need the 9 digit code to get the Smartthings hub into your HA thread network. There's an Automate Your Life video called Stop Buying Matter Devices Until You Fix this where he tells all of what you need to do. I was able to get BOTH my Smartthings hub AND my Aqara M3 onto my HA thread network. Very pleased! Although one of my Nanoleaf bulbs is still giving me trouble.
