The legend of the 'Hell Courtesan' was about a beautiful courtesan, a daughter of a samurai, who was "kidnapped by his enemies and was sold to a brothel".
She started to call herself "Hell Courtesan" after an encounter with a Buddhist monk, Ikkyu Sojun, who was known for his taste for sake and prostitutes.
According to the story, Ikkyū met the Hell Courtesan during one of his visits to the pleasure district. Santō Kyōden's book from 1809, All Records of Drunken Enlightenment of Our Country, tells that she "found him dancing with a bunch of skeletons instead of being entertained by dancers and geisha. It occurred to her that he may not be an ordinary human being."
She then became his disciple and achieved enlightenment.
So I think they might actually be punk moshers from the underworld.
If you have any kind of firewall on your network, you might make sure it's not blocking that port with a rule.
Here's a couple screenshots from my setup in case that helps.
The config in NPM
The config in HA's configuration.yaml
Try adding just the NPM IP and HA IP first, then add the docker internal network as well if you still have issues.
Just government drones. It works on paper since it's from renewable sources.... And if you squint real hard and don't look at the big picture of how it's actually working out (like this article).
If you are primitive camping, a big bucket of water and a spade or sturdy stick are your friends. Thoroughly douse the embers, break up the coals, douse it again for good measure, then scatter any remaining cool ashes outside the campsite.
Pretty cool, I'm glad you got it working. I hope that's the gold standard going forward - we should be able to open up, inspect, and even fix our own devices. That used to be the case for most electronics.
