The short version

  • Only MQTT has a free tier, so it costs nothing to try first.
  • Each has a real cost: Ecobee installation requires a C-wire in most cases, necessitating professional installation for some users unfamiliar with HVAC wiring; 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
  • They diverge on capability: Ecobee covers Room Sensors, MQTT covers Publish-Subscribe.
