Not an issue - TEsted working with LG Ducted

My LG Units are a 17.1kW Ducted
B55AWYU3G5 - Indoor Unit
and
ABUW55G7SB0 - Outdoor UNit

and I have installed myself a PREMTB100 controller.
My PCB is sitting on a jumper wire to the PREMTB100 controller

Everything seems to be working just fine right now!

I've disabled the LG Wifi dongle now as it seems to make the integration a little flakey - which is expected as the LG dongle is itself a little flakey, to the point where we couldn't rely upon it to use it from our mobiles.
Now we have your code installed, it's rock solid :-)
Thankyou!
here's hoping I get time to help out

Thanks! I added it to the list. Good to hear it works with ducted units too.

Are there things you still use the PREMTB100 for because they're not supported by the controller? Maybe zone control?

We use the controller for a quick easy override / kids can control it.
still haven't fully adopted Home Assistant everywhere,
plus it looks good on the wall.

I'm not using the zone control - which is supported, but plan to hook up our 3 zones and add more in the future.

I'm not sure if this is the right place to ask, but I have an LG air conditioning system that it is built into my apartment, almost like a "central" system (I believe it is a "ducted" system just like @bleughb's). Unfortunately, this means that I have no idea what my indoor or outdoor units are; all I know is that my thermostat is an LG PREMTB10U, and it has 3 wires - power, ground, and signal.

My understanding is that the usual use case of this community is with an LG wall-mount unit, connected to an outdoor unit, which supports a device like the PREMTB10U via the CN-REMO connection. However, most people do not have such a thermostat/remote installed by default, so they open up the indoor/wall unit and connect this device instead.

I am hoping that I should be able to replace my PREMTB10U with this project's PCB, pretty much exactly as it seems @bleughb has done. Does that sound right - that I could simply connect the same 3 wires from my PREMTB10U (power, ground, signal) to this project's PCB, and it would work? I know you can't guarantee anything, of course, but what do you think?

Regardless, thank you so, so much @JanM321 for your tremendous work on this project!!!

I expect that to work. For what it's worth, in issue #1 someone else replaced a PREMTB10U controller with the PCB.

Some of the LG controllers also support an older protocol for which there is an ESPHome implementation here, but I hope my project will work. The hardware side is the same, it's just a completely different message format.

Regardless, thank you so, so much @JanM321 for your tremendous work on this project!!!

You're welcome! Please let me know if it works :)
