I am tired of seeing this. Everything was working fine for last month, then suddenly, several devices started showing as unavailable in the ST classic app. I ran Z-Wave repair and no issues were found. I checked again after 2 hours, devices were still showing as unavailable. Checked just now and except for one device, all other devices are showing fine. This keeps happening every 25-30 days. I run Z-Wave network repair every day but no issue is reported. Is it because something at ST end is having problems?
