Is your feature request related to a problem? Please describe.

It's possible/probable that my RIN will likely change over time for any reason, however the H-A energy dashboard doesn't seem to like having concurrent sources for pricing (or consumption/generation) set up, I believe this means there'll be data loss if I update to a new entity in the energy dashboard.

Describe the solution you'd like

It'd be nice if I could edit an existing integration to change the target RIN

Describe alternatives you've considered

A template to use in the energy dashboard. I think I need to do this anyhow to sum the cost of two RINs. It might be worth mentioning to users that this is best used via template for anyone, though for the reasons above, if it's not feasible to edit the already-created devices.

Additional context

Thanks for the cool integration!
