I am on C7 2.4.4.156
Zwave has been very stable over the years. Recently, lights are sluggishly are not at all turning on or off. I am thinking Zwave ghosts. I have not added any devices for some time. I have shutdown hub, removed power for 15 minutes and rebooted, no change. here is my zwave details. How can I find out which is polluting the zwave network: 2.4.4.156
I'd start with the devices that say pending.
I'd say the battery sensors wouldn't slow the mesh down.
How about that ZEN17 Gate relay? Get that working. Maybe some other stuff out there is routing through it.
edit: Let me just say you got me looking at my Z-wave details page after a very long time of blissful ignorance with its being 'down' with Zip, and now being on ZWJS. So thanks a bunch. 
I excluded gate control relay. Tried the mimimote button to turn off bedroom ceiling lights. Chrome browser said
Jack Minimote: button 1 pushed BROKEN
Unexpected Error
An unexpected error has occurred trying to load the app. Check Logs for more information.
Error: Cannot get property 'id' on null object
Firefox did not say that but deleted the button rule and recreated i . Still same result on Chrome and Firefox no longer says broken. But mains powered MasterBedroom ceiling lights maybe a problem. Will try to exclude and include on that.
