I have installed Home Assistant to Sonoff NSPanel Pro according to this guide:

Finally I installed the Home Assistant.
When I tried to connect to my Home Assistant, I got a certificate error due to my local home assistant using my own CA in local area network.
I have tried to add my own CA certificate to android

But it seems to me that it does not work. Home Assistant shows a certificate error and I cannot ignore it.
How can I add my own CA certificate to Sonoff NS Panel Pro?
