The short version

  • Only MQTT has a free tier, so it costs nothing to try first.
  • Each has a real cost: Meross limited geographic availability with regional variants for US, EU, UK, AU, JP; MQTT mQTT is an open-source protocol standard with no commercial pricing; not a commercial product
  • They diverge on capability: Meross covers Apple HomeKit, MQTT covers Publish-Subscribe.
  • Prices and features above were last checked on 30 August 2026.

Answered from the vendors’ own pages

Meross: Does Meross have geographic availability limitations?

Yes. The Meross website shows regional product variants for US, EU, UK, AU, and JP markets, indicating not all products are universally available worldwide. Regional thermostat models differ between markets, suggesting firmware or voltage differences prevent cross-region use.

Source
MQTT: Does MQTT have a commercial license cost?

MQTT is an open-source communication protocol and standard. No pricing is published because MQTT itself is not a commercial product for sale.

Source
Meross: Do all Meross devices support energy monitoring?

No. Only certain plug and switch models including MSS305, MSS715, and MSS815 include energy monitoring. Basic plugs like MSS110 lack this feature.

Source
Meross: Do Meross sensors require a hub to operate?

Some sensors do require a hub for full functionality. Door/window sensors (MS200H) and water leak sensors (MS405H) appear to require an MSH-series hub for proper operation, limiting standalone capability.
