My hub for the past week has been having extreme Z-wave communication issues. Device commands lag or never reach the device. Routines and SmartApps with z-wave fail with almost 100% predictability. The hub event logs show numerous Z-Wave power cycle events, 12 in the last hour for example. I’ve tried numerous Z-Wave repairs but I am starting to suspect the Z-Wave modem is bad.
Support has been responsive but has been unable to offer any solutions.
Anyone else experience this before?
