Hi all and thanks for your time! I am new to Arduino but a computer nerd in my normal life.
I have a battery management system that I would like to be able to turn off/on my inverter in my Van. The battery management system is designed to switch an inverter that has a single pole single throw ON/OFF switch. My inverter has a momentary switch both on the device and on a remote that plugs in through an RJ9 cable. This remote shows ON /OFF state by switching on a LED. It seems to me that one could use an Arduino board to hijack the signal from the battery management system and then check the LED state and then send the on/off signal to the inverter. Is this doable? Can someone point me to some resources that might help? There are many other folks building systems similar to mine and I would love tofigure this out and give back to the community.
