2 Three-Tier System Architecture
Terminal Perception Layer: FC810L collects fan & valve status, transmits data via LoRa wireless;
Transmission Layer: NC302 gateway aggregates all data and uploads to Alibaba Cloud via cable; GW12 repeater eliminates signal blind spots for high-rises;
Cloud Management Layer: EMS cloud stores all energy data, split into tenant mini program & property PC backend with independent access authority.
3 Eight Core Advantages
LoRa Cable-Free Design Cuts 30% Renovation Cost No wall cutting or pre-buried wires for old buildings, only replace thermostat. Save labor & wall repair cost, finish single floor within one day.
No-APP WeChat Mini Program Easy For Tenants Bind room via WeChat without installation, adjust temperature & pay bills anywhere without visiting property.
Automatic Prepaid Lock Solve Arrears AC locks automatically with insufficient balance, advance payment reminder sent, recover service after recharge to reduce disputes.
Three Modes Cover All Building Types Low-cost time mode for apartments; high-precision energy mode for malls; hybrid system for mixed parks, compatible with one cloud platform.
Remote Timing Save 15%+ HVAC Power Property set idle temperature limit to reduce cooling/heating output for vacant areas, cut long-term electricity expense.
Cloud Deployment Without Local Server All data stored online, no local server or fixed public IP required, lower project investment.
Bidirectional Real-Time Fault Alert Reduce Inspection Labor Offline & abnormal equipment notified to managers & tenants, eliminate floor-by-floor patrol, cut 70% meter reading work.
Permanent Data Storage For Dispute Verification All energy, recharge & operation records saved permanently, export bills for dispute checking.
