VESync integration

Has anybody noticed any “odd” behaviour with the VESync integration or just VESync products in general?

I’ve got a Levoit 300S Air Purifier and it regularly disappears off the network, from the app, resets its filter status etc. Levoit were so stumped they actually shipped me another which is running alongside the existing one and suffering exactly the same issues.

I have ruled out ALL manual interventions with these devices, something between their app and the HA integration is causing the devices to misbehave as previously described. I can see from the notifications from the app and also from within Home Assistant these changes are happening when there is nobody awake (the “new” one reset its own filter status to 100% at 2am last week).

the builtin integration is definitely bonked. I get plenty of errors in my HA logs regarding my 300s smart purifier with it working intermittently

Thanks for coming back.

The original device constantly removes itself from the VESync app and both the old device and its replacement do random things like resetting their filter statuses and turning themselves off or to a different mode when they are set to “Auto” and the controls locked (ruling out manual intevention).

They don’t really need to be connected to HA but since when did that stop anybody but it’s just a faff trying to keep it online in HA.

I am new to the community but have used Home Assistant for years including the VeSync integration. The last working version of VeSync was 2025.2.5. I have tried upgrading since then and every subsequent version is broken so I always have had to roll back. In the later version a lot of the earlier products like outlets don’t work anymore. Roll back with 2025.2.5 and all works again.
