Screenshots None

Additional context have other devices connected as well which are working just fine

• viomi.vacuum.v8
• chuangmi.camera.021a04

Home app shows change filter soon warning and controlling the air purifier through home app does not work.

"Call to device timed out" can indicate that your device might be overloaded due to processing to many requests. You can try to reduce the chunk size with the propertyChunkSize to a lower number like 5 and see if that helps.

After changing the chunk size, restarting both homebridge and the device, it works alright again. Thanks!
