Seeley / Breezeair Control Protocol?
(1/1)
ludzinc:
Hi All

Looking for some help.  I'd like to integrate my home AC control into an Automated Home network, and to do this I plan to attempt to decode the protocol the controller uses.

First step was to open a unit and share some pics.

Second step is to ask the internet if anyone has done it before so I can lean on your work ;)

Thanks for any help / tips / advice and I'll share any future succcess with you all.

Cheers!

 |O how's it going , any success this looks similar to my controller which died a few weeks ago  :-// .
So I would really like to know if this is some sort of serial connection similar to the Reverse cycle A/C posted here .

So I tool would like to know if I can insert a arduino or ESP8266 device to control my Evaporate cooler.
Rerouter:
Its a little hard to work from your pictures (extreme angles, rather than flat)

But from that 4 pin connector at the bottom, you have Ground to plane, the fat trace will be power, The third pin connects directly to the pic microcontroller from what I can see, and while I cant see what the 4th pin does, I suspect another data line or as simple as not being present

If its 1 data line, I would expect something similar to K-line, an older industrial 1 wire protocol, Its pull down only,
If 2 wires, then maybe something else. if its direct to the CPU there are not many things it could be.

any progress on getting some automation?
