ecobee says a red light bar on Switch+ indicates privacy mode.
Helpful context
ecobee devices can use lights for privacy status, voice assistant behavior, setup feedback, and device state. The exact meaning depends on whether you are looking at a thermostat, Switch+, sensor, or another ecobee product.
For safety and accuracy, Button Light Guide separates ecobee pages by device family instead of assuming one light pattern applies to every ecobee product. Start with the model page when available, then compare the color and blinking pattern.
