Zrobiłem z ciekawości trzecią próbę, tym razem ESPHome zainstalowany na moim Linux Mint (bazuje na Ubuntu)
cezary@Lenovo ~> pipx install esphome
installed package esphome 2025.12.6, installed using Python 3.12.3
These apps are now globally available
- esphome
done! ✨ 🌟 ✨
cezary@Lenovo ~> esphome version
which esphome
Version: 2025.12.6
/home/cezary/.local/bin/esphome
cezary@Lenovo ~> ls -l ~/.local/bin/esphome
lrwxrwxrwx 1 cezary cezary 56 sty 15 21:06 /home/cezary/.local/bin/esphome -> /home/cezary/.local/share/pipx/venvs/esphome/bin/esphome*
cezary@Lenovo ~> mkdir -p ~/esphome
cezary@Lenovo ~> cd ~/esphome
cezary@Lenovo ~/esphome> esphome dashboard .
I jak by to powiedzieć 
u mnie działa.
Kod dokładnie taki jak poniże na każdej platformie, ESPHome z pakietów pipx, kontener Docker na NAS i AddOn w HAOS.
