The short version
- Only Arduino Cloud has a free tier, so it costs nothing to try first.
- Each has a real cost: Control4 requires professional installation and dealer network, with no self-install option; Arduino Cloud the free plan allows 2 connected devices, 5 variables each and one day of data retention
- They diverge on capability: Control4 covers Integrated Control, Arduino Cloud covers Device Connectivity.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Control4
- Requires professional installation and dealer network, with no self-install option
- Limited device compatibility; works best with Control4-certified ecosystems
- Subscription required for remote access and advanced features
- System complexity requires technical knowledge or ongoing dealer support
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
