ESP32 and WCS1800 based photovoltaic powermeter
- uses WCS1800 as current sensor
- uses ADS1115 as 16 bit analog to digital converter at 5 volt operating voltage
- uses YF08E as 3.3 volt to 5 volt level shifter to convert the i2c signals
- works as WLAN client and AP (AP chooser included)
- WebUI with IP address 192.168.4.1
- mDNS hostname hallometer.local
- DNS hostname hallometer.local (WLAN AP mode only)
- manual zero point adjustment of the hall voltage
- measures up to +/- 35 amps dc
- measures up to 20 volts dc
- measures voltage, current, power, charge and energy
- charge, energy and running time are stored every 6 hours automatically or manually via web ui
- SDA - GPIO 21
- SCL - GPIO 22
