Yesterday I upgraded from AppDaemon 3.0.5 to 4.0.1 and while the upgrade itself went smooth thanks to the excellent docs, I had to rollback because of performance problems.
I use appdaemon to switch my lights and with 3.0.5, it works excellent. After the upgrade to 4.0.1 though, when I pushed a wall switch, it sometimes took 3 to 5 seconds before the actual light went on. This is in contrast too AppDaemon 3 where the light responded instantly.
Any idea what may be causing this?
