Actually when opening the VeSync app I got a pop up message letting me know the requests are too frequent. Can anyone advice how to correct this in Home Assistant?

@AlxSZP
Possible fix for this might be to reduce the update frequency.
This can be done with the file editor by opening
"/homeassistant/custom_components/vesync/init.py"
and changing (in my case this was line 77) the number in
"update_interval=timedelta(seconds=30),"
to
"update_interval=timedelta(seconds=120),"
or another (higher) value that fits to your needs :-)

@ade7dan1 thank you so much. I went extreme for now and added 300 seconds to see if it holds up with two active devices. And it's holding!!!!

I will bring it down little by little to understand the ratio per device and get it closer to ~120 seconds

Any updates on this one? I just started getting the same error
