How can I see Home Assistant Devices?

Hello,
I tried several times to use Home Assistant. It seems that I can connect, but the IOS App don‘t show any devices. Why?
Second, I tried to reset the RS90, but if I try it. It says invalid pin. Why? Can I change it anywhere?

Another question is that I can see 2 Apps with Chinese Letter. What is it? Can I delete it?

Thanks,
Chris

You can delete any app from the RS90.

For Home Assistant we have seen issue getting devices if there are some add ons running on your instance.

Try to disable few and test.

I have several Add Ons running on my HA. I cannot disable all of them. I tried some but it didn’t help. Do you know which could be the problem.
I need a stable solution. I cannot understand that it is not working.
Please check which configurations I can check to see the devices.
