Hey there, i did some more work on the reverse engineering and prepared a HA App that is running the fake server.
- install app from GitHub - weidi/ha-addons · GitHub
- point api.huum.eu via DNS rewrite to your local HA IP (where the app is running), i use adguard but you can use anything like pihole or your internet router (if it has the feature)
- start / restart sauna so it picks up the new ip as target
- Use this package config

Enjoy local control!
What is missing is the steamer feature as i dont have any.
