Redesign of Settings > Devices & Services > Helpers tab

[dougiteixeira]

The new integrations page looks great, which leads to a little frustration with the helper entities page where we also manipulated some settings.

I suggest implementing something similar to the integrations page, each block would be the type of helper, clicking on it would show each entity configured in the place where the configuration entries of the integration page are.

In addition to maintaining consistency, I think it greatly improves the handling of helper entities.

Edit:
The integration page already works for the helpers, so the job would just be to change the Helpers page/tab.
Test your instance for the utility meter (or whatever you use): http://x.x.x.x:8123/config/integrations/integration/utility_meter

Example block for the Helpers page/tab:

When clicking on entity information, it would be redirected to the entities page (Settings > Devices & Services > Entities) already filtering the entities of that configuration entry, where it has the same resources as the current Helpers tab.

Example helper page (already implemented integration page works here...):

However some helpers show the error Error occurred loading flow for integration counter: No module named when clicking on the button ADD HELPER...
