MQTT Broker does not show ny devices

You saved my life here. I was getting errors while ‘testing’ to update to non-lite version due to its size (from sonoff to tasmota) and i could only use .bin
As you’ve said, I tried the UPDATE and set the .gz version there and MQTT worked well.

Now I’'ve a minimal issue/curiosity. Some devices appear as Tasmota and 1 as MQTT (i played with them in different days)… Anyone knows WHY some are Tasmota “integration” and one as MQTT “integration”??
