VeSync Integration causing throttling

[JeffSteinbok]

The problem

I think the VeSync integration is causing throttling by the VeSync servers.

When I call their endpoint from a browser on my home network, I get this: https://smartapi.vesync.com/

{
    "traceId": "1721940128566",
    "code": -11103086,
    "msg": "internal server busy error"
}

If I turn off polling in the VeSync integration, things seem to start working again. I get this response:

{
    "traceId": "1721940393496",
    "code": -11000086,
    "msg": "illegal argument",
    "module": null,
    "stacktrace": null,
    "result": null
}

If I access VeSync from Cell or a different VPN, it all works, indicating that it has to do with my source IP location.

I do have a LOT of devices (15 or so) which may mean I need to drop the polling interval and do it manually? Unsure. Either way, this just started happening a day ago or so.

I too am having this issue. At least once a day I see the same connectivity issues. I currently have 3 air purifiers in VeSync. Each time my connection drops it lasts for at least 3 hours.

[matthewpapa07]

+1 Seeing this as well

[jmunchies1]

Also just experienced this for the first time today. I have 3 x Core 400S air purifiers that have worked fine in HA for a while now. I just upgraded HA from 2024.7.4 to 2024.8.1 and noticed that VeSync integration wasn't working. I thought something went wrong on the upgrade but then the VeSync Android App says server error and won't load either so I'm guessing my VeSync account had been throttled. Hopefully this can be rectified somehow.

+1. stopping HA auto polling solved the problem.

Having the same issue, did you turn off polling from the integration setting?

[jmunchies1]

I originally turned off polling in the integration setting but have since turned it back on. So far been ok for 24 hours, wonder what the threshold is. In any case, can the devs create a setting to reduce the polling rate? I would still like it to update but less frequently so we don't get throttled.

[mattryyc]

I'd like to also see options around polling rate added here, assuming that would solve the issue. The throttling also means that VeSync app can no longer control the devices (not just HA), so this is a big impact to the device functionality when the throttling kicks in.

[mtnbiker777]

Add me to the list of people having this issue.

[jmunchies1]

Had this issue happen again when going from 2024.8.3 to 2024.9.1. it seems that major HA version upgrades will trigger it for me but minor (in-month) upgrades don't.

Devs please see if there's a way to reduce the polling rate please.

I also have the issue and I would love a poll rate setting as others mentioned.
