Unable to discover a device at address

[mppilat]

After Haas Core and system update my yeelight_v2 custom integration no longer discovers one of my lamps.
I did not change anything in configuration

Now lamp is automatically detected by default yeelight integration, can be added and controlled. Howevert default integration lacks means to enable nightlight, which was possible in yeelight_v2
