I started seeing the following in my Activity Feed yesterday evening “Body is XXX bytes”. XXX changes with each message.
I had one switch that quit responding to any programmed changes and always showed it as being off, even if it was on. I removed it from the system and had it rejoin and it seems to be working again. I also made changes to modes, but I don’t have any of my own apps installed, only a few that are on the system. That’s about when it started last night.
I have a few smartapps installed. I did uninstall one for sonos (mood music), because I could never figure out how to get it to work. Maybe that was the culprit. I removed it about the same time I did the network repair.
It seemed to have that in activity randomly, not at a time when an action should have been taking place.
