Diagnostics information

I wish to add gas consumption to the energy dashboard, however all entities created by ViCare integration miss device_class (in my case, device_class: gas), according to:

https://www.home-assistant.io/docs/energy/faq/#troubleshooting-missing-entities

I tried to add device_class manually under Developer Tools > States, and this works, however entity's settings are rewritten in about 10s or so.
