Does the Home Assistant app only use http or should I be able to use https also to talk to the Home Assistant server?
Hello,
The Home Assistant app only uses http to communicate within the local area network.
If you have any features you want to implement or more ideas, you can share them here.
Hi,
The obvious feature, in this case, would be to also support https within the local network. 
Thank you very much for your feedback. We will conduct research on related technologies and conduct a technical evaluation. If the evaluation passes, we will add this function in subsequent versions.
