# Tibber Data to a IoT internet data service
# =============================================================================
# 
# Description:
#   This script fetches electricity price information from Tibber API and uploads
#   it to an IoT service. It handles both the complete data set as base64 encoded
#   JSON and individual current price values.
#
# Usage: 
#   ./upload_tibber_values_to_iot.sh <tibber_api_key> [iot_upload_key]
#
# Arguments:
#   tibber_api_key  - Required. Your Tibber API access token
#   iot_upload_key  - Optional. Key for IoT service (https://iot.hdev.io/). 
#                     If not provided, a new one will be generated and displayed
#
# Outputs:
#   - Complete price data as base64 encoded JSON
#   - Current price value
#   - Current price timestamp
#   - Download URL for accessing the uploaded data
# =============================================================================
