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

Yeelight

  • Requires iOS 16.2 or later, per the App Store listing
