Control hot tub over wifi - control box Hawk

[darkwin]

Hello, I have a hot spring hot tub with a Hawk 76840 control box.
I would like to control the hot tub via wifi.
Does anyone have any further data on the control box?
I think there could be a way to connect an Arduino board to the control panel?
Does anyone know how the control panel communicates with the controller?

Currently, Hot Spring does not have any way to control the hot tub via wifi.  That should change next year, but I don't have any information I can share.  Anything you would attempt would be completely a diy setup.

Hi, yes I know there is no wifi controller.
So I would like to try this with an arduino.
I would like to know how the HEAD Control communicates.
Is it i2c?
Does anyone have the pin layout of the connector?

My guess is that what you are wanting is proprietary and not available to the public. In 26 years, I have never seen a pin layout for a proprietary digital control system on any brand.

If you find one, please post it so we can all see.

Hi, I've seen a lot about other devices. It's a great community in the homematic field.
I was hoping to get to know a few in this area.
Unfortunately, my knowledge of microcontrollers is not that good.
I measured J9.

Blue 3.9V
Yellow 12V
green 0.06V
Red 0V (gnd)
black 3.9V
white 0.06V

Check out the I hacked my 2018 Hot Springs hot tub so I could control the temperature over the internet thread. I believe it has what you need.
