Hi there,
I have 3 smartsolar 75/15 connected to a Rspberry pi 3B+.
I've already read the documentation about the Tx and Rx functionality, it seams that if I have plugged in a Ve.Direct to USB cable (which I have..) I can't use the remote on/off function on the Rx pin.
I just made some test with the solar charger plugged into the Rpi3 via Ve.Direct, charging and displaying the data on the touch screen. At this point if I make a short between Rx and Gnd pins, I do not lose connection, and the smartsolar stops charging. Then when I relese the short, the smartsolar starts charging again.
My plan is to instal a relay to make the short between Rx and GND on demand, keeping everithing connected to Venus OS at the sme time.
It is safe to do so?
Thank you
