It took six months to figure out how to get Alexa to change the temperature in the built in Echo of the Ecobee4 thermostat in my house. It would always respond with, "I didn't find any smart home devices." Turns out the Ecobee skill is not enabled by default for a device it is built into. Asking how to enable it or how to make it work lead no where as well.
