MULTI-CHANNELS DIMMERS
It’s ideal for smart home systems—whether you’re dimming lights, running a fan, or powering a pump
AC Power Router Controller
AC Power Router Controller is an all-in-one development board based on the ESP32 microcontroller (WROOM/WROVER) designed for building AC dimmer and relay control systems. Perfect for makers, hobbyists, and DIY enthusiasts who want to quickly spin up smart home projects, industrial automation, or power monitoring setups without the hassle of breadboarding everything from scratch.
MODULES RBGRID
Build your home power system step by step, selecting only the modules that match your requirements. Each step adds new capabilities while maintaining full compatibility with previous components.
Zero-Cross & Voltage Sensor Module
The heart of your monitoring system - without it, nothing works.
This combined module is the absolute minimum requirement for any RBgrid deployment. It provides critical grid synchronization through zero-cross detection and accurate voltage measurement - two fundamental functions that enable all other measurements.
Why it's essential:
- Grid Synchronization: Precise 50/60Hz timing reference for all measurements
- Voltage Monitoring: Real-time grid voltage for power calculations
- Phase Detection: Required for power factor and direction sensing
- Safety Isolation: 4kV galvanic isolation protects your ESP32
What you can monitor with Step 1 only:
- Grid voltage (RMS)
- Frequency monitoring
- Voltage quality analysis
- Basic grid status
MEASURE CURRENT & POWER
Current sensors complete your monitoring system, enabling full power analysis, energy tracking, and cost calculations. Choose between two technologies based on your installation requirements and safety preferences
Option A: ACS-712 Hall-Effect Sensors
Direct measurement for maximum accuracy
Hall-effect sensors provide precise bidirectional current measurement for AC systems. Ideal when you can safely interrupt the circuit during installation.
Available models:
- ACS-712-10A: Electronics, LED lighting
- ACS-712-20A: Home appliances, HVAC
- ACS-712-30A: EV charging, heat pumps
- ACS-712-50A: AC Grid, Home generation (solar panel, battery).
Option B: SCT-013 Current Transformers + Adapter
Clip-on installation without cutting wires
Non-invasive current transformers that clip around existing wires. Perfect for retrofitting existing installations without electrical work.
Available models:
- SCT-013-010: 10A max - Individual circuits
- SCT-013-030: 30A max - Standard home circuits
- SCT-013-050: 50A max - Main supply, large appliances
