Is there a health check I can add to home assistant, that will not only make sure that home assistant has started, but also all the integrations have been started also?
The reason is that other containers, like node-red, depend on home assistant being fully started before they start, otherwise they produce errors, and some of the flows don’t activate unless home assistant is fully started.
If you just want to know when HA has fully started & loaded all integrations, you could use the homeassistant_started event as a trigger to let your other containers know it’s safe to start.
Not sure how you’d pass that info to your other containers because I know next to nothing about Docker, but hopefully it’s enough to get you started.
