    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.

    Board:

    $18.

    Switchpro and spod do this. But significantly more expensive and limited expandability.

    Let us know how it turns out. I am interested to see how you like this set up. Also what other BT devices are you planning to manage aside from the wireless camera? Are you adding more cams?

    I looked into WiFi for the switch control; I think it would have better signal strength. However the demo apps I looked at were a bit more complex to build, dealing with the sockets and tcp stack. Not an area I wanted to get involved with. Bluetooth is 30 feet, even thru the firewall / cabin I think it'll go 10 feet. We'll see.

    The demo bluetooth apps are super simple to compile and if you're not picky on labeling, already exist.

    I doubt it is going to be 100% reliable, for my use cases I can have hard switches for backup (example - onboard air compressor, easy to put a toggle switch under the hood too).

    Right now my use case is:
    Compressor

    I plan to add:
    Fridge
    Several different lights

    Stretch use case:
    Lockers

    My main goal is to avoid spaghetti wiring everywhere, and the associated tear down and rebuild. Basically looking to do what a SPOD etc would do, without the investment and physical switching.

    For anyone who has a smarthome; it would function a lot like that, but just be really limited and local.

    That looks pretty cool. $210 though.

    Or... Skip wireless transmissions & phones/tablet reliance altogether and just install a wired camera and screen. This means you can have it on 100% of the time if you like, or use the included remote to switch to a second camera...or turn the screen off.

    $109 (it went up since I bought mine)...

    That’s a good option too @Markuson . China produces something for everyone. And if it has circuits I loves it.

    The WiFi camera works full time as well, it also has a recording mode. Only difference is no wires into the dash and no dedicated display. I use it infrequently, but it’s there if I need it. One Siri command away.

    I am actually surprised how many viable wireless switching options there are. I spent some time reading up on a 15 relay rf setup. $60 and 2 remotes. Range in 100s of feet. Remotes had like 30 buttons. It’s way more capacity than I need, but for someone with many different lights would be perfect.

    China makes everything. :)
    From paper clips to iPhones...

    But anyway... their cheapo camera & screen work a charm. It’s on 100% when wheeling. Helpful.
