The short version

  • Only Arduino Cloud has a free tier, so it costs nothing to try first.
  • Each has a real cost: Arduino Cloud the free plan allows 2 connected devices, 5 variables each and one day of data retention; Sonos s2 app has not received significant updates beyond bug fixes since launch, making it difficult to search within music services
  • They diverge on capability: Arduino Cloud covers Device Connectivity, Sonos covers Multi-Room Audio.

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

Sonos

  • S2 app has not received significant updates beyond bug fixes since launch, making it difficult to search within music services
  • Stereo pairing and bonding speakers into zones has technical limits on the number of devices
  • Only receives stereo audio from AirPlay 2, not supporting Dolby Atmos for spatial audio
