Portal home page says "Not Connected"?
You will need to be at home to fix a disconnected thermostat.
Follow these steps to reconnect a thermostat:
Locate the gateway; this is a small black or white box that says “Digi” and should be located near your modem and router.
1. Unplug the black power cord.
2. Wait 10-30 seconds and plug the power cord back into the gateway.
This should reboot the gateway and restore your connection. After 5-10 minutes check your energy account website to see if the green “Online” icon is on the “Home” page.
If your system is still not working, contact Customer Care for further assistance.
