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

OpenHAB

  • Requires a 64-bit Java 21 JVM to be installed and maintained separately
  • Oracle Java is explicitly not recommended by the project because of potential licensing restrictions
  • The recommended hardware is a dedicated Raspberry Pi 4 or newer rather than shared hardware
  • Some version upgrades require additional manual steps run through a separate upgrade tool
