Where each one falls short

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

AVEVA PI System

  • Pricing is not published and comes through an account representative
  • The vendor is moving to a subscription commercial model, so perpetual licence expectations no longer hold
  • Made up of several separately named components, including PI Server, PI Vision, Edge Data Store and the adapters and connectors needed per data source

Home Assistant

  • Add-ons run only on Home Assistant Operating System installations, and Container installations have no access to them
  • Thread and Z-Wave are controlled by add-ons, so a Container install has no out-of-the-box support for either
  • A Container installation means bringing your own Linux host with Docker and handling updates by hand
  • The recommended install path expects dedicated hardware such as a Raspberry Pi 4 or 5 with at least 2 GB of RAM, an Odroid, or an x86-64 machine
  • Every documented hardware option requires a wired Ethernet connection
