ZPC ver_1.7.0: OnOff cluster - "Off" command does not switch off Z-Wave plug device

[yblin00]

Using ZPC ver_1.7.0, I added a Z-Wave plug device.

• Switching On works correctly.
• Switching Off does not work.

The device turns on successfully, but it does not turn off when sending the Off command.

Logs:
