My Hubitat experience has been rock solid and flawless for weeks/months, especially since the zwave antenna upgrades. After noticing a few strange things over the past few days I took a look at my logs and zwave logs. The Ecolink Chime is doing "something" on zwave every 4/5 seconds.
Pull the battery/power and wait 10 seconds then power it back up. See if that does the trick.
Otherwise model # would be helpful to look up a manual for it.
The chime is ISZW7-ECO, its the 700 series Ecolink chime. This unit has an internal backup battery. Plug/unplug didn't help, and exclude/join didn't either.
What fixed it was reseating the SD card, in case anyone else runs into this.
Thanks for the solution. I just wanted to let you know that my Ecolink chime stopped working. I saw your post, removed the SD card and reseated it. The chime is now working again.
