What makes the diffference?
I don't know which devices show and which dont in your case, but if you see Scenes and Groups and not, say, Switches, then that's because Scenes and Groups don't use MQTT (because Domoticz's MQTT bridge doesn't support them so I had to fall back to the JSON API which does much more but lacks all the advantages of MQTT).
So it's probably an issue with your MQTT configuration. Start by double-checking that you
have websockets enabled in your MQTT broker (hint: if the port is 1883 then you are not using websockets). If you are using Mosquitto, you can look at the links in
Reacticz's readme on github, they explain how to enable websockets, or see for example
NietGiftig's configuration in an older post.
