Thanks for the hint I did not know about Nabu Casa.

Although I am not clear about the benefit of the service. I thought I could achieve the same kind of access with simply forwarding ports 80 and 443 from my router to my home assistant. Is there anything wrong with my intended setup?

Using a VPN does work for restricting outside access, however I found that for me this was not convenient enough for two reasons:

1. I would need to setup a VPN server at my home network
2. I would need to connect to my VPN everytime before trying to access my smart home devices

Since I am on the same journey as OP and tried it just recently, I have one thing to add about openHAB:

It does not come with actual login credential handling. If you want to make your smart home accessible from outside your home network I cannot recommend openHAB.

I am currently going with Home Aisstant mainly for that reason.

How is this a sweater reveal? The sweater was visible during the whole procedure!

I’d love to switch places with that chair

Same. Was für einen Vorteil würde es mir denn auch bringen zu löschen?
