  • 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

Lutron Caseta

  • A single Caseta bridge supports up to 74 devices, capping the system before requiring additional hardware
