Inspired by the success of my WiFi backup camera, I’m going to tryout Bluetooth switching. I looked at the solid state options, and was uninspired by the price ($100 and way up) and didn’t want to deal with finding a mounting location. I didn’t want to deal with aftermarket switches ( not enough blanks in my lx anyway) pulling cable to the dash, or any of that. So the odyssey begins. I ordered a basic 4 relay 12v Bluetooth board. It will slave the higher power relays for the stuff (lights, arb twin, fridge etc). It’s easy to add more boards ( they are tiny). For now control will be via free iOS app. I might mount a dedicated tablet or phone later on, if this all works out.
