I have this idea for a project but I'm keen to see what those with more experience think.
Anyway, my wife and I and our kids are living off-grid with a solar PV array plus battery bank and inverter etc.
The inverter is a Selectronic SP Pro, and doesn't come with wireless connectivity standard. You need to buy another product for $300-$400.
Anyway, I'd like to send the USB data from the inverter via bluetooth to my computer to display it 10 metres away (indoors).
It comes with software, SP-LINK, to monitor and diagnose the data from the inverter, but currently you need to plug a physical USB cable into the inverter and your laptop right next to the inverter.
Anyway, i've been doing some research and I wonder if it would be pretty simple to connect an arduino (a UNO or Mega maybe? or could you use a Nano or Pro mini?) to a bluetooth module such as a HC-05, and pick up that bluetooth COM connection on a remote laptop (10 metres or so away) like you're plugged in??
So you would be using the arduino to simply send and receive any comm data from the bluetooth link from the laptop, back to the usb connection of the inverter.
What do you think?
Appreciate any helpful suggestions.
