Bobbie glows in different colors. What do they mean?

Bobbie's button is surrounded by a lighted ring that indicates the different states of Bobbie. The different colors of Bobbie have different meaning when Bobbie is not installed and after having being paired to an MClimate Home account.

Before installation:

Constant yellow: The device is ready to be installed. Bobbie is waiting for Wi-Fi settings.
Purple: Bobbie is loading. This color indicates a state change. 
Blinking blue: The device is trying to connect to a Wi-Fi network.

After installation:

Breathing green - It means the power is disconnected from the water heater. The app appears blacked out.
Breathing yellow - It means power is connected to the water heater. However, this doesn’t necessarily mean the water heater is heating, as it may have reached its own thermostat temperature.
Breathing red - It means the power is connected and there’s energy consumption at the moment, aka the water is heating.
