If anyone is interested I have created three new entities which work alongside the "Hildebrand Glow IHD Home Assistant integration on GitHub. Now you can read the Cost Per Hour, Per Week and Per Month as shown on the Glow Meter but not available ordinarily. Copy the code below into your configuration YAML file, restart HA and add them to your dashboard. Hope this helps someone!!
