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

Google Home

  • Web version (home.google.com) has limited controls compared to the mobile app
  • Battery-camera live streams on the web app auto-stop after 5 minutes
  • Requires compatible Google/Nest or third-party smart-home hardware - it is a control app, not a standalone product
