The short version

  • Each has a real cost: OpenHAB requires a 64-bit Java 21 JVM to be installed and maintained separately; RudderStack on the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
  • They diverge on capability: OpenHAB covers Vendor Agnostic, RudderStack covers Data collection.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

RudderStack

  • On the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
  • The free plan allows 250,000 events a month
  • Growth starts at $265 a month for 1 million events, with volume sold in tiers up to 25 million
  • Overage is charged as the gap to the next tier's price rather than per event, so a small excess costs a full tier step
