I am relatively new to home assistant so please forgive my ignorance. Currently I have let’s encrypt and Phillips hue emulator running on my raspberry pi. I see according to the documentation, they both listen on port 80. Let’s encrypt requires that I forward port 80 through the firewall. Are there any security concerns that I need to address before I forward port 80. I rather not have my devices published on the Internet.
Can I restrict Phillips hue emulator to only respond to local devices?
