I see only about a sentence about "Full remote device sync" in the document I found here:
https://docs.hubitat.com/index.php?title=Hub_Mesh
Support (@bobbyD, @gopher.ny ) seem to be recommending turning "Full remote device sync" off if your hub is experiencing certain load-related issues (slowdowns, locking up). What does changing that setting do? Are there any negative impacts to our automations? Are there any specific recommendations for the use and configuration of Hub Mesh?
