Setting auto mode turns device off about homebridge-levoit-humidifiers

Can confirm it’s doing the same thing for me as well on the 300s

Works great, thanks!

Thanks for the bug! I have also been seeing this but haven't had a lot of time to dig into it.
I should be able to take a look this weekend.

So far as I can tell and based on my limited familiarity with the Vesync API (I sniffed out the request from their app using Charles on my phone), the API call to the Vesync API looks good and right, and mode should be set to "auto" (and it is!) — gonna check and see if debug mode gives me anything interesting.

Update: going from Humidity mode to Auto actually sets the switch to be off.

[12/8/2021, 12:28:45 AM] [Levoit Humidifiers] [DEBUG]: [SEND COMMAND] Sending command setSwitch to Humidifier with ({"enabled":false,"id":0})...

A couple additional observations:

• If I switch to Auto (which turns it off), then hit Off (it stays off) and then Auto, it turns the humidifier back on, and in Auto mode (Sending command setSwitch to Humidifier with ({"enabled":true,"id":0})...)
• If I switch to manual Humidity, and then Off (which turns it off), and then Auto, it turns the humidifier back on, but stays in manual Humidity mode

I don't know enough about the inner workings of Homebridge to fully diagnose, but it sounds like maybe there's some state management that's not being handled correctly, or a switch listener not being set properly?

Thanks @kreeger. Still haven't taken a look, but that's very helpful. From your logs, it seems like switching to Auto is not calling changeMode, but setSwitch. I'll try to get to this in an hour or so

I've published this fix in [email protected]

Here are the two PRs: #4 #5

The auto mode target level still can't be adjusted currently FWIW.

seems to be working on my end as well. or at least it doesnt just shut itself off.
