The short version

  • Each has a real cost: MQTT mQTT is an open-source protocol standard with no commercial pricing; not a commercial product; Z-Wave Alliance manufacturers must hold a Manufacturer ID, which costs $7,500 per year for two MIDs and a further $7,500 per year for each additional MID
  • They diverge on capability: MQTT covers Publish-Subscribe, Z-Wave Alliance covers Mesh Networking.
  • Prices and features above were last checked on 30 August 2026.
