It would seem to me the user gets one or the other. Why not adding both

[IceBotYT]

Why not adding both

It is simpler for users because the meter check takes a while. Users can always go to the config flow again to add a outage counter or another smart meter.

PECO needs updates to the branding (for a separate PR though):

• The "Peco Outage Counter" and "PECO Energy Company (PECO)" integrations should co collected under a "PECO Energy Company" brand
  • I believe this will also solve the missing brand image for "Peco Outage Counter"
• The name of "PECO Energy Company (PECO)" integration should be improved to explain what it provides compared to the outage counter integration

Looks great, thanks @IceBotYT 👍
