There’s a newer plugin app called Ecobee Thermostat (by eZLO) .
The instructions call for you to install the app, then add the Ecobee thermostat by adding devices (like you would a Z-wave device). Add Device>Thermostat>Ecobee. Then provide credentials to link your account.
Has anyone had any luck installing an Ecobee thermostat using this plugin?
It says it’s by “eZLO”, but I doubt it’s by Ezlo Innovations.
