I am using android homeassistant app to add matter device (bulb) to Homeassistant. The app is connected wifi network which has no internet access (192.200.20.xxx), ip6 is enabled. App can reach homeassisnt server at 192.168.200.xxx:8123. I am NOT able to add device via local network w/o internet. However, if I use wifi network which has internet access and IP6, it can add the matter device. But that exposes device to internet which i dont want. Why am I NOT able to add device via local network which does not have internet access via app?

192.168.200.xxx has internet access and HA server is on this network with internet. 192.200.20.xxx network has no internet service.

on android, the home assistant app uses functionality provided by google play services to do matter device commissioning. google play services requires an internet connection.
you can remove internet access after setting up the device, if you like.

ok. how i can remove internet acsess?

i mean, how are you creating a subnet without internet access in the first place?

why would you switch networks? just temporarily change the firewall/routing rules of the network that doesn't have internet access so that it does, set up the matter device, then remove internet access again.
other options - apple ios devices can do matter setup without internet access, and you can use a bluetooth dongle connected directly to the haos system to do setup of devices in bluetooth range.

I dont use any apple IOS product! If I add BT dongle to HAOS, can add device via android app?
dreamy prism
no, when doing setup via a bt dongle, you have to reconfigure the matter server add-on a bit, then add the device using the matter server web ui

keep in mind that matter was designed with the assumption of a simple "flat" network, so with anything more complicated, you're going to run into issues with various things.
it sounds like you're using matter over wifi devices? those are a bit more forgiving, but you might run into issues if you add thread devices later.
only the phone needs internet access, so you might be able to have some firewall rules to allow the phone and deny other devices.

I thought since phone is on mobile network with internet access and wifi is w/o internet access, app should have access to google while on wifi network w/o internet access.!

android doesn't really work that way, it only uses one network connection at a time.

After 7+ years to HA use, this is first time adding matter device (bulbs) , no idea of how I can not use wifi and still add matter device. Is there any other way to add matter device?

Added firewall rule to allow phone to access intenet from any network. Matter device added to HA! Thanks.
