I have an event alert when Homeseer is showing the Ecobee 'Online Status' is Offline. I checked the Tstat, and it shows connected to Internet. I can control the Ecobee from the Ecobee Android app through Internet/Cloud. And, in Homeseer I can adjust the Ecobee controls and Ecobee tracks with changes. So everything seems to be working, yet the Online Status in Homeseer shows the Ecobee offline. Other times it will show 'Offline' and I can't control it through Homeseer. Happens probably once a week on average. Goes away on its own in some minutes. Don't have to re-register or anything.

Can anyone provide any insights how the online/offline connection is established, what it means if it shows offline, where the breakdown might be happening?
