LG Air Conditioner Model LW8017ERSM

Describe the bug After upgrading to version 1.2.0, my HomeBridge logs are getting filled with error logs about SwingModeCharacteristic. My AC model only has manual control of the vents, not remote or app control.

Symptom check

• Does your unit appear in the Home app? Yes
• Is the current on/off state, temperature, and mode being reported? Yes
• Does your unit respond to the controls? Yes

I believe it is specifically referring to this block of code. Which as you can see from my debug logs, I do not have a airState.wDir.vStep only airState.wDir.leftRight

[sman591]

Good catch, I didn’t expect this. Let me think about how we should support this

Is functionality broken, or are the logs only littered with errors?

[kb1ibt]

Littered with logs only as far as I’ve tested, it’s been cool enough today that I didn’t have the ACs on to do much testing after verifying 1.1.1 and 1.2.0 fixed #12
