Hello,
I am trying to reverse engineering a wired air conditioning remote in order to automate it via openHAB...
Once opened the remote I faced myself with a three wires connection:
after digging around I have discovered that the SIG wire is a signal that "instructs" the central air condition engine on what to do...
I have founded this article that describe a similar case, but my level of knowledge is minimal:
I am at step one: how do I build a digital circuit to reverse engineer the signal from SIG wire? anyone else have better ideas?
Thank you all
I am trying to reverse engineering a wired air conditioning remote in order to automate it via openHAB...
Once opened the remote I faced myself with a three wires connection:
- GND : Ground
- 12V: Power
- SIG: I assume “signal”
after digging around I have discovered that the SIG wire is a signal that "instructs" the central air condition engine on what to do...
