Need help with battery device attributes

[WillCodeForCats]

I'm looking for help with some battery info (since I don't have batteries).

I want to know if the device attributes (for entity sensor.solaredge_b1_device) are fixed values or of they can change over time. The documentation calls them "battery nameplate information" which means to me that nameplate values should never change as if they are printed or attached to the device itself, and why I chose to implement them as attributes of the device.

However, if they can change over time, ones that can change should probably be added as their own sensor entities for statistics instead of attributes. These are the attributes I'm looking at:

• batt_charge_peak
• batt_discharge_peak
• batt_max_charge
• batt_max_discharge
• batt_rated_energy

On my charge up last night, and during a charge this morning from the sun, those values stayed static for me, despite the charge not always operating at peak (5,000) due to the BMS throttling the charge.

If it helps, changing the I1 storage charge and discharge limits also have no impact on the B1 Device attributes you mention.

My B1 Device attribute values:

Batt charge peak 5,000
Batt discharge peak 5,000
Batt max charge 5,000
Batt max discharge 5,000
Batt rated energy 9,700
Device ID 21,471
Manufacturer SolarEdge
Model SE Energy Bank
Parent device ID 1
Serial number ********

Mine is the same, don't think it changes.

Here is my Battery Data:

Batt charge peak 7.850
Batt discharge peak 12.550
Batt max charge 8.475
Batt max discharge 12.288
Batt rated energy 13.800
Device ID 112
Manufacturer SolarEdge
Model SolarEdge Home Battery 13.8kWh
Parent device ID 1
Serial number xxxxxxxx

Here are change events from my system. I've excluded the serial number.

Okay so I'm seeing is that it's possible for the _peak values to change.

I will get a pre-release out shortly to move those values over to sensors instead of device attributes.

[WillCodeForCats]

Release v2.4.9-pre.1 splits 4 of them into sensors instead of attributes.
