• Added option to configure sensor names in configuration.yaml, see the sensor_names option. Note that when you use or change this option, it will create new entities. This means that you will have to update your lovelace cards, automations and/or scripts that use the entity_id. Note that you can still rename sensors afterwards from the UI. After the change, you can manually delete the old entities from the Developer Tools.
• Added the mac address to the attributes of the sensors
• New sensors will be named according to a new convention: mi_sensortype_mac (e.g. sensor.mi_temperature_A4C1382F86C)(default) or mi_sensortype_sensor_name (e.g. sensor.mi_temperature_livingroom) (with sensor_names option). Your current sensors with the short nameing (e.g. mi_t_A4C1382F86C) or manually modified names won't be renamed, unless you use the sensor_names option.
