Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ESPHome

  • ESPHome runs only on supported microcontrollers; the project recommends ESP32, ESP32-S3, ESP32-C3 and ESP32-C6 and advises against ESP8266 for new projects
  • Support for ESP32-H2, RP2040 and other newer chips is documented as less mature
  • Large displays and some sensors do not work well on ESP8266 because of its limited RAM, which is roughly a fifth of an ESP32

Nest

  • Pricing not published in support documentation; individual product prices vary significantly
  • All Nest products require Google Home ecosystem integration for full functionality
  • Smart home devices operate only within the Google Nest ecosystem; limited third-party interoperability
  • Support and product documentation dispersed across Google support rather than centralised Nest site
