A fix for this issue has been deployed, and we have verified that the issue has been resolved.

We have identified the source of the API degradation and have put a temporary mitigation in place. We are preparing a long term fix and expect to deploy it overnight.

We are currently experiencing an interruption to Thermostat Online Applications. Please be advised that ecobee thermostats will continue to operate normally on the set schedule and by manual adjustment, including all in-progress energy-savings events. The ecobee app, web portal and third-party apps may be temporarily unavailable. Thanks for your patience as we are working to resolve this issue as quickly as possible. We apologize for any inconvenience and will keep you updated.
