That was somewhat my motivation behind this. As of late, I had several Hub freezes and needed to restart the hub every other day, this was with tonesto's version installed and running. No measurements of metric's done though
Since changing over to the MakerAPI and HubConnect version I don't see any freezing or slowdowns anymore.
Any major concerns here as to what needs to be available? I use Homekit as my UI and for presence detection (setting a virtual switch on arrival/departure). So far I have not detected any problems in that regard. Or better, my wife hasn't detected any issues so far, keeping WAF high is the goal!
