    local_key: !secret local_key  # (required) local key of the device
    device_id: !secret device_id  # (required) device id 
    update_interval: 10 # (optional) frequency to update the status in seconds, default: 10
    current: 5  # (optional) attribute id for current
    current_consumption: 6 #(optional) attribute id for current consumption
