Hey everyone,
for Christmas, we got a hoot for our kitchen. Since we needed one that is exactly 80cm wide, the options have been pretty limited. The model we got is the SilverLine Slim Deluxe. Unfortunately, there is no out of the box way to make this hood smart. However, inside the hood, there is a standard 10-pin connector like this one, connecting the front panel to the control unit. I did’t have much time yet, but I was already able to figure out that (like in the picture), pin 1 is VREF (+5v), and pin 8 is connected to ground when the light is switched on.
Since the front panel has a 7-segment display including a dot (indicating the light on/off), I assume that asides from VREF, there are 8 cables controlling the different segments, and probably one wire indicating the button clicks (probably through different resistors). My overall idea is, to try figuring out the rest of the cables, putting an ESP in between, and sending states to HA or simulate button clicks through GPIOs.
With a big family however, I don’t have much time I can put into the project. So if anyone else has a hood like this as well, feel free to contribute your findings about the different pins, or how to provide power to the ESP.
If I make progress, I’ll share it here as well.
