Worst customer-service experience ever. I paid an electrician twice to install and update the transformer Ecobee recommended. When I called again, support demanded photos of the wiring, transformer, and electrical meter—even though everything is about 10 feet up the wall. I am not an electrician and should not be expected to perform electrical troubleshooting for them.
The representative coldly ended the call because I could not provide those photos. No apology, compassion, or effort to help. Their support is extremely difficult to reach, lacks competency, and seems focused on blaming customers and avoiding warranty responsibility—even after paying extra for professional support.
The device also becomes extremely hot, which feels like a serious safety risk. Ecobee, you owe me reimbursement for the electrician fees and this defective product. Buyers, beware.
