Where each one falls short

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

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

Slack Workflow Builder

  • Limited to Pro and above pricing tiers, requiring paid Slack subscription
  • Maximum 15 conditional branches per workflow, limiting complex logic paths
  • Connectors must be explicitly configured per integration type
  • No native web interface for non-Slack users
