[Bug]: The write handler for the characteristic 'Selected RTP Stream Configuration' on the accessory 'Shed' was slow to respond
### Describe the bug

Nest cameras take up to 10 seconds to start showing in Home app. Sometimes don't show at all.

Running Hoobs 4.2.5 and Nest Cam 7.5.1. Performance the same on latest homebridge also. 

Have tried downgrading to 7.5.0 but had same issue.

Logs show an RTP Stream Configuration issue.
