Where each one falls short

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

Arduino Cloud

  • The free plan allows 2 connected devices, 5 variables each and one day of data retention
  • Free accounts are limited to 25 compilations a day and 10 trigger notifications a day
  • The Maker plan at $72 a year lifts devices to 25 and retention to 3 months, still for a single user
  • Team pricing jumps to $1,000 a year
  • Two years of data retention and unlimited ingestion require Enterprise

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
