An esp32, a mqtt node and iftt hooked up to google/Siri goes a long way

Unfortunately, mqtt autodiscovery seems fraught with bugs...

I just want some way for devices to publish/report their model numbers and what features they offer/support so everything can auto-configure itself rather than requiring me to manually set MQTT paths/filters/parsers for every device I get.

Specifically... The mqtt server should advertise itself on the local network via mdns. The devices should auto-discover the server. Therefore, no config required of the device beyond wifi username/password.

Then dashboards/controllers (who should also auto discover the server via the same method) should be able to send some message to some well-known topic on the server to find all connected devices.
