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

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

SmartThings

  • Cloud-dependent with no offline operation; requires internet and Samsung servers for all device control
  • Cloud communication adds latency compared to local hubs; device response delays up to one second
  • Confusing app transition between SmartThings Classic and SmartThings Connect with certain automations only working in one app
  • API changes requiring paid subscriptions starting October 2026 break third-party integrations like Home Assistant
