Precision Smart Switching & Metering Series
Enterprise smart devices engineered by Shenzhen Corunsmart, delivering end-to-end telemetry, high surge tolerance, and seamless multi-ecosystem integration.
Why Tier-1 Integrators Standardize on ESP32-C3
The global shift toward decentralized building automation, energy telemetry, and unified cross-vendor ecosystems has placed the ESP32-C3 SoC at the center of commercial procurement strategies.
Enterprise Zero-Trust Security
Unlike legacy microcontrollers, our ESP32-C3 smart plugs integrate hardware-level cryptographic accelerators. Featuring RSA-3072 secure boot, AES-128/256-XTS flash encryption, and digital signatures, they guarantee device identity and data confidentiality across untrusted corporate networks.
Matter-over-Wi-Fi Native Support
By leveraging the 32-bit RISC-V architecture running at 160MHz with 400KB SRAM, our plugs natively support IPv6-based Matter protocols. Enterprise clients can bridge hardware into Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings without relying on proprietary cloud bridges.
Sub-Watt Metering Precision
Engineered for mission-critical carbon accounting and sub-metering, our solutions feature integrated high-accuracy shunt resistors paired with calibrated energy metering ICs (BL0942 / HLW8032), delivering RMS voltage, current, active power, and aggregated kWh metrics with <0.5% margin of error.
Macro-Industry Solutions & System Topologies
From distributed edge intelligence to multi-tenant real estate infrastructure, our customized ESP32-C3 plugs act as local computing nodes for demanding commercial environments.
Commercial ESG & Smart Campuses
Deploy real-time load profiling across university facilities and offices. Automated peak-shaving routines manage heavy inductive loads during high-tariff windows via local cron schedules, independent of continuous cloud connectivity.
Telecom & Edge Node Power Cycling
Remotely reboot unmanaged server racks, 5G base station switches, and IoT repeaters. Embedded ping-watchdog routines autonomously cycle relay power when IP backhaul loss is detected, drastically cutting truck rolls.
EV Charging Sub-Metering
Ideal for level-1 fleet maintenance and residential parking spots. Built-in zero-cross switching circuits prevent contact welding from capacitive inrush currents, supporting long-term resistive loads up to 16A/20A continuously.
Hospitality & Property Management
Seamlessly integrate with PMS platforms through private MQTT brokers or Tuya enterprise SaaS. Monitor abnormal consumption patterns from air conditioners and appliances to preemptively identify maintenance failures.
Hardware Platform Architecture: ESP32-C3 vs Legacy Alternatives
Comprehensive benchmarking highlights why modern IoT infrastructures require RISC-V edge computing over outdated 8-bit and older Wi-Fi chipsets.
