Just got my new HE today. Got it set up okay. I took an existing Ecolink Contact Sensor and excluded it from Smartthings. Then I included it with HE. It shows up as a device. But when I open and close the contact, it does not consistently and accurately report to HE the correct status of open vs close.
I then opened up a brand new, never used, Ecolink Contact Sensor. Paired to HE okay. But it too reports the correct status only sporadically. I tried rebooting the hub, but still the same problem.
