Good to Know
- Same app, same features across all three — custom high/low alert thresholds, graphing/trend history, auto-sync over Bluetooth. The pricier sensors don't unlock extra app functionality.
- Dew point & VPD are calculated automatically from temperature/humidity readings on every model — useful for grow tents and greenhouses.
- 1-year warranty on all three sensors.
- App compatibility: iOS 11+ / Android 9+.
- The G1 WiFi Gateway is optional for every model — sensors work locally over Bluetooth without it; the Gateway only adds remote/internet monitoring.
