Answered from the vendors’ own pages

ESPHome: Is ESPHome free to use?

Yes. ESPHome is free and open-source software. The Desktop App, Device Builder, components, and recipe tools are all available at no cost.

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
ESPHome: What is the cost to run ESPHome?

ESPHome software itself is completely free. Hardware devices and components used with ESPHome vary in cost depending on which microcontrollers and IoT devices you choose.

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.

ESPHome: Does ESPHome require a subscription or license fee?

No. ESPHome is open-source software with no subscription fees, license costs, or commercial restrictions associated with its use.

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.
