Good day! I have OpenEVSE v4. Is it possible to additionally connect Arduino (UNO) and arrange data exchange between them? The garage where I charge the car is outside the WiFI network, so I want to connect the GSM module to the Arduino UNO and control the charging process via mobile communication. Is it possible? I need to know exactly the possibility of connecting OpenEVSE and Arduino. Thank you in advance for your cooperation!
If the RAPI commands are enough to do the controls you need, the arduino will communicate using the TX/RX pins. The arduino can be powered by the OE 12 volt supply also.
