Unable to configure 'power_on_behavior' for SPLZB-134 device (UNSUPPORTED ATTRIBUTE).

It seems the device doesn't support it, could you provide the debug log when changing this pre z2m 2.0?

See this on how to enable debug logging.

Rolling back to 1.39.0 (i had backup) the option to configure 'power_on_behavior' is no longer visible.

What is weird it that the entry on this website show it as being supported https://www.zigbee2mqtt.io/devices/SPLZB-134.html.

If it was never supported can we prevent Z2M from trying to configure it at startup and removal from GUI please?
