HS-FS100 custom sensor - plug info?

[MFornander]

I have a few HS-FS100 around the house and they work great. I'm wondering about the physical/logical specs for the plug. It capable of sensing both light and water given the right cables.

I would like to create my own sensors since I'm guessing the plug has power and perhaps connected to some ADC pin on the board. Can you provide the "pin definitions" of the plug so we can start writing custom drivers and sensors for the HS-FS100?

Cheers,
Mattias

Requests have been made. HomeSeer has not released any info on the pinout for the TRRS plug.

Homeseer sells a water cable and a light sensing cable.

Hmmmm I'll reverse engineer it myself then. I bet there is a GND, VCC, and either an ADC or some I2C/SPI/TX/RX on the other pins. BRB
