So, I’m attempting to use a waterproof shower controller to control something other than the mixer it was intended for. I was looking to use a wireless controller (see here) but that may be a little beyond this first attempt.
Instead I’m attempting to use a wired version instead.
So the controller I want to hack is the Vado Identity IDE-147A-C/P or now called the Vado SENSORI
So far I’ve passed a multi meter across all of the pins of the mixer to see what it’s outputting and the attached is what I found.
Basically the controller is 5v DC and the power is on pins 3 (-ve) and 2 (+ve). I’ve connected 5v to it and, sure enough, it lights up and shows the default screen. It then displays E1 which is to be expected I guess as it’s not connected to the mixer.
I’m thinking that pins 1 and 4 are likely to be tx / rx but I’m not sure which is which or what the next step would be to work that out.
I’ve tried to read digital values on pins 1 and 4 from the controller and they set to 1 as soon as I add power and stay there.
I’ve also tried reading analog on pins 1 and 4 from the controller and not much happens there either other than they both go to a particular voltage and stay there.
So the next step is going to be reading the same from the mixer to see if it shows up anything.
Then I’ll start looking into serial reads from the mixer and try replaying that to controller to see what happens.
So, assuming it is serial then I need to work out which baud rate to use but I think that rather than attempt to work it out it may be quicker / easier to just try the standard rates and see if I can read anything.
I only have an uno at moment with a mega coming tomorrow so I’ll hopefully be able to read from serial1 and write to the serial monitor then.
Nothing much to ask right now other than any advice on where to go next and I’ll continue to update this thread with my findings…
