protocol between in.touch and controller? #50

Open Elwell opened 1 month ago

Hi - Have you ever identified the pinout and dumped the traffic between the in.touch receiver and the spa controller itself? I know your geckolib is based on sniffing the transmitter to internet traffic, but I'd like to work on (likely an ESP32 esphome based) a single box replacement for the in.touch pair that connects directly to Home Assistant

Total guess (based on the other products that can plug into that port like the 'in.stik') is that it's actually a USB connection with a with DIL pinout rather than the normal "consumer" connectors. but that's as far as I've got with investigations - I'll hook up a logic analyser once weather's a bit better

IIRC correctly, someone on the Home Assistant forums went as far as discovering that RS-485 was being used., but there might be more than just RS485 on the 8 pins of the CO ports.

There is an attempt to start a thread over in the Esphome/feature-requests repo: https://github.com/esphome/feature-requests/issues/2893

Most of the bits of digging/reverse engineering people have done have been scattered around. Another issue here had a lot of useful pin probing info: https://github.com/gazoodle/geckolib/issues/8#issuecomment-876631237
