Where each one falls short

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

Fronius SOLARWEB

  • Only works optimally with Fronius hardware; monitoring of third-party inverters is not supported
  • Advanced historical analytics and forecasting features require paid premium subscription
  • Requires stable internet connectivity and cloud connection for all functionality
  • String-level diagnostics require onsite inspection to identify which panel within a string is failing

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
