Fleet Deployment
LuxOS provides batch installation tools for large deployments:
# LuxOS CLI tool for fleet management
luxos-cli install --ip-range 192.168.1.100-200
luxos-cli install --csv miners.csv
luxos-cli update --allCurtailment / Demand Response
LuxOS's standout feature is native curtailment integration:
- Automatic load shedding when electricity prices spike
- Demand response program integration (ERCOT, PJM, etc.)
- Scheduled power profiles — time-of-use optimization
- API-driven control for custom automation
- Graceful ramp-up/down to protect hardware
Curtailment can save 10-30% on electricity costs for operations in deregulated markets with dynamic pricing, making LuxOS particularly popular with large-scale North American operations.
