Please add an additional note to your excellent Integration explanation:
Do not perform a firmware upgrade to the tp-link KASA EP10P4 if you plan to use it with Gladys Assistant. The firmware upgrade from 1.0.5 to 1.1.1 causes the EP10P4 to use the newer KLAP protocol, which causes the EP10P4 to not be discovered in a devices scan. Without the firmware upgrade, the device is usable with Gladys.
Regarding your many contributions to Gladys, thank you!
