MQTT : Selecting topic to publish

[ciberyan]

Hello
Newbee here so I apologize in advance
I have miraculeously set my RPI DOmoticz to publish data to a HiveMQ free server
BUT it plublish all the devices, including some, for example my AC current consumtion at a quite high frequenecy leading to a lot of useless traffic
Is there a way to choose what devices or Datas I wish to publish ?
Hope it make senses for some of you guys !
Thanks in advance
