Saving settings

[Vovick1971]

Hello.
Thank you for the work you've done. I have been looking for a similar project for a very long time. It is completely suitable for my tasks.
In my device, I use ESP 32 and ZMPT101B modules to measure mains voltage.
I have one unclear point.
On the "channel settings" page, I select the voltage measurement channel (for example, L1 voltage), the sensor type (ZMPT101B), set the
coefficients, save the settings (SAVE button at the bottom of the page), everything works correctly, but if you restart the EPS32 web
interface page, or restart the module itself, then all settings return to default values (SCT013-000). In this case, incorrect values are
output. You have to set the parameters again.
Setting the checkbox to allow real time editing, but don't forget to save your settings also has no effect.
I can't figure out how to make the set values persist.

Thank you.
