Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
SmartThings
- Cloud-dependent with no offline operation; requires internet and Samsung servers for all device control
- Cloud communication adds latency compared to local hubs; device response delays up to one second
- Confusing app transition between SmartThings Classic and SmartThings Connect with certain automations only working in one app
- API changes requiring paid subscriptions starting October 2026 break third-party integrations like Home Assistant
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
