The short version

  • Each has a real cost: Arduino Cloud the free plan allows 2 connected devices, 5 variables each and one day of data retention; Shelly premium features limited to cloud-based functionality; local control requires separate setup
  • They diverge on capability: Arduino Cloud covers Device Connectivity, Shelly covers Local Control.

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

Shelly

  • Premium features limited to cloud-based functionality; local control requires separate setup
  • Device-specific capabilities vary; not all features available across entire product range
