Re-adding a Device With New ID

[thick gyro]

A couple years ago I was exploring solar in my area with a smaller setup and wanted to have the data in HA. In order to do this I bought a smart plug (Kasa) with energy monitoring and it would report power which I piped into the solar dash. All good.

Since then I have upgraded to a “real” solar system and decomissioned the old one. The other day I wanted to use the smart plug for monitoring the energy for something else but I’m stuck in a loop of issues and data loss.

If I remove the smart plug from HA or remove the entity from the energy dash I lose all the solar history, I would like to keep that.
If I use the device anywhere else the energy dashboard adds solar because the entity is still there.

What I want to do is re-add the device to HA with a new unique identifier or name but I cant figure this out. I think the ID is based on the MAC address so it recognizes that it's the same plug and thus I'm stuck in this loop.

You can remove the smart plug from HA. The old entity ID will stay in the energy dashboard. The old statistics will stay.

Then you can re-add it with a different entity id, and re-use it, breaking the connection with the old data.

This is my problem, When I re-add it, I don't see a way where I can "force" the entity ID to be anything other than default, which ties it back to the old plug

Can you:

• change the entity id to something unique
• then delete it
• then re-add it?

I assume it will not re-add with the modified ID.

or at least I hope not

[thick gyro]

ok This is my current ID.

so you think change this to something like *_2. delete the plug, then re-add it?

[stone swan]

hmm nevermind. When you re-integrate the device it automatically calls it that?

[thick gyro]

yes

[stone swan]

hmm

You may have to also delete the entity_id after removing the device, don't know if you did that.

it will show something like "Not provided"

in my .storage/core.entity_registry is this. I wonder if I can change the device_id?

seems risky

or more likely the config_entry_ID
