under development

Update:

2022-10-20: PCB Layout design nearly final. Planed release date end of october 2022

General facts:

• ESP32 with Web Interface (MQTT)
• Din Rail System for integration to Grid box
• Current Sensing with SCT013-000 or 030 sensors (Isolated system)
• Voltage Sensing with ZMPT101B Current Transformer (only 3 phases and N to be connected)
• RF433 Receiver and Transmitter Modul for Smart Home integration
• 3 external interfaces
• 3x DS1820 or
• 1x DS1820 : 1 x Pulsecounter Interface(digital Meters with optical interface); 1x Analog in / out
• OLED for showing information directly
• 3V3 for peripherie that is not needed can be shoot down by switching of supply voltage to minimize current in system
