The short version

  • Only MQTT has a free tier, so it costs nothing to try first.
  • Each has a real cost: MQTT mQTT is an OASIS standard messaging protocol maintained by a standards committee, not sold by a vendor; there is no company-controlled price list, subscription, or edition to compare because implementations are independent open source or commercial products built on the spec; Control4 requires professional installation and dealer network, with no self-install option
  • They diverge on capability: MQTT covers Publish-Subscribe, Control4 covers Integrated Control.
