Question: How to keep history for external voltage for each phase?

[bj00rn]

Wouldn't it be nice to have a a separate sensor for external voltage for each phase for history purposes?

Correct me if i'm wrong, In the current implementation, per phase values are implemented as state attributes and are not recorded.

Phase history is helpful when trying to understand if SSO/EH fault codes are related to grid voltage.

Im using a workaround is to create a template sensor to grab phase voltage..

This is of course doable. We have lots of attributes on different entities so maybe we should extract all of them? Thoughts on this @henricm ?

[henricm]

I've also thought about this actually. I think it's a good idea to extract the values for each phase to be sensors of their own. Or are there other attributes too? I'm thinking about the sensors that have L1, L2, L3 attributes.

[argoyle]

There is a pos/neg somewhere and probably something else but most are L1, L2, L3. I'll see if I can find the time to do something.

For diagnostics it would be a nice feature. I guess downside is there will be a lot of sensors 🤓 .

• external_voltage => external_voltage_l1, external_voltage_l2, external_voltage_l3
• grid_current => grid_current_l1, grid_current_l2, grid_current_l3
• external_reactive_current => external_reactive_current_l1,external_reactive_current_l2,external_reactive_current_l3
• etc..

Maybe it's a good idea to keep the original the original sensors (including state attrs too). For sensors like grid_power I guess the general use case is looking at all phases combined rather than individual phases.

Think also this feature would be good, i have solved this today by creating templates:

Yes, I didn't plan on removing the current entities, just add new for each phase.
