   investigating
   Some people may be having trouble using our Thermostat Online Applications. We’re happy to share that ecobee smart thermostats will perform as usual—they’ll continue to operate according to the set schedule and by manual adjustment, including all energy-savings events that are already in progress. We’re working hard to figure out why the app, web portal and third-party apps are temporarily disconnected. Thanks for your patience. We’ll keep you updated, and apologies for any inconvenience this has caused.
