- Version 2.1, corrected for daily totals
- Version 2.2, problem wih some logins solved
- Version 2.2.1, minor issue improved. When power is 0, the interval was set to 1 hr so no pulses were set during this time even when power returns All rights reserved Do not use for commercial purposes
- This project is a PlatformIO version, and converted to use ArduinoJson6 and latest WifiManager solving some issues with the older wifimanager.
- This project is dependending on several libs which are defined in the platformio.ini file and will be downloaded automaticly by platformio
This bridge will get the data from the GroWatt web interface (API) and create S0 pulses and led flashes Each pulse/flash will suggest 1 Watt
On GPIO 5 a PC817 optocoupler is connected
PIN D1 ---- PC817 (anode, pin 1, spot)
GND ------- PC817 (cathode, pin 2)
PC817 p3 ------ Inner 3,5mm stereo jack plug
PC817 p4 ------ Outer (2x)
On GPIO 4 a resistor (330 ohm and red LED are connected in series):
PIN D2 ---- Resistor 33Ohm) ---- (Long LED lead ---- LED ---- Short LED Lead) ----- GND // red
PIN D3 ---- Resistor 33Ohm) ---- (Long LED lead ---- LED ---- Short LED Lead) ----- GND // yellow
_by setting Led to BUILT_INLED you can use the internal led on the print of the wemos instead of this external LED
After uploading the sketch to the Wemos D1 mini, connect to the AutoConnectAP wifi. Goto 192.168.4.1 in a webbrowser and fill in all data including GroWatt credentials.
Added OTA (Over the Air update) support use the platformIO configuration defined in the INI file to configure hostname or IP adress of the bridge to send firmware updates over the air.
- Settings are saved on the Flash (wemos mini) and will reloaded from startup.
- Resetting the bridge will clear all settings (WIFI and Username Password).
