Yes.
The ‘6 devices’ and ‘56 entities’ reported by the MQTT Integration were all created via MQTT Discovery.
Previously, I had defined them in configuration.yaml. However, you cannot define devices this way, only through MQTT Discovery. So I scrapped all the MQTT-based entities I had in the config file and created scripts to generate them via MQTT Discovery.
Here’s a fragment of one script that creates binary_sensors (just the first binary_sensor is shown):
create_binary_sensors:
