Integrating LG ThinQ washer dryer with local control (LG FWY937WCTA1)

Configuration
1

Hi all,

I have an LG FWY937WCTA1 (13kg wash / 7kg dry) washer dryer, which uses LG ThinQ for smart integration, and I’m hoping to get some advice from anyone with experience integrating this (or similar LG models) with Home Assistant.

My setup and requirements

  • The machine will not be granted internet access (except maybe to grab a token, get set up, or similar). I’m very strict on privacy, so any integration needs to work locally or via a reverse-engineered solution.
  • My priorities are local control and monitoring, rather than cloud-connected features.
  • Ideally, I’d like to be able to:
    • Monitor detergent and softener levels (the machine has an autodosing system).
    • See cycle progression/status (wash/dry stage, remaining time).
    • Trigger a cycle remotely or via automation (e.g. start a dark wash/dry cycle at a time when energy prices are low).

What I’d like to know

  • Has anyone managed to integrate this model (FWY937WCTA1) with Home Assistant?
  • More broadly, has anyone successfully integrated LG ThinQ appliances locally (washer/dryer in particular)?
  • If so:
    • What sensors and entities does it expose in HA (cycle status, time remaining, door open/closed, detergent tank levels, etc.)?
    • Have you had success sending commands (start, stop, select program) locally?
  • Any pitfalls or limitations I should be aware of?

If anyone has practical experience with this machine or other LG ThinQ washer/dryers in HA, I’d really appreciate hearing about your setup.

Thanks in advance!

Hello rexehi4709,

If you read this, it should answer those questions.

Thanks for your response, I have read this but it doesn’t answer my questions because of my first requirement to be airgapped from the internet:

This feature works via LG ThinQ cloud. Therefore, an internet connection is required.

I’m hoping for anyone who has got ThinQ devices (this one in particular, if possible) to work locally connected.

Look in Github for something else, but that integration is maintained by LG itself and I heard it does all the things.

Good luck.

Thanks, I found a couple of leads on Github, not sure yet if they will do what I need to do but will dig around.

If anyone has any experience with these or experience with this particular washer/dryer it would be great to hear from you:

Hi!

Take a look at my rethink project. It is exactly about running ThinQ devices locally. I’ve developed it for an AC unit, but it’s likely that other devices share a similar protocol. Even in the best-case scenario, some work would be necessary in order to decode the messages specific to the appliance.

Feel free to contact me on github if you’re interested.
