I have been running hass on rpi pretty stable. Today I decided to bring up hass on another rpi and put in SSL Cert so I could hit it remotely
Ported my config over with not problems. Using local host mosquito for mqtt, when I restart hass from the console or cmd line and it comes back. Mqtt goes nuts , I watch the mqtt messages getting posted several per second from hass until I stop the service , then of course the mqtt messages stop. After a few restarts in comes up stable.
