Regularly resend HA discovery Data

[SciLor]

The Feature

If I am restarting my server, including HASS and my MQTT Server, the discovery information is gone and HASS doesn't find the device anymore.

So the discovery information should be resend once a while to mitigate this problem.

Restarting a server is not something that happens during normal operation. Also, when you enable retention, this will not be a problem.
Additionally, the UI has a button to resend those topics.

We on purpose decided no to resend those topics periodically to reduce the load on the ESP.

Home Assistant and the mqtt servers restart regularly for updates. Is there any mqtt command / API endpoint to automate this process?

Its missing in the docs (I will add it to https://jomjol.github.io/AI-on-the-edge-device-docs/REST-API/). But just call http://<IP>/mqtt_publish_discovery
