K1 max used material length

[natuurwaarnemer]

I saw that one of the entities is the sensor.k1max_6f16_used_material_length counting from 0 to max length in cm.
in creality itself it shows the total gram, i was wondering if this also could be available. otherwise i was wondering how you made that calculation of the max length. I am going to use that in a small integration whereby i would like to calculate the max used filament/gram on a spool..
I know that there is a spoolman app (i also recently use) but i hate the prerequisities for that e.g. flashing moonraker software on k1 max, connection via internet to spoolman, then connection via internet to HA. while with your websocket the data is already avalaible.

any thought on this?
