Slewflash, I have no idea, but I suspect it has something to do with the MCU configuration for the lockout mode of operation. I agree, lockout should be lower than standby. However, SWM’s main purpose for lockout mode is to prevent accidental turn on.
The physical lockout method (unscrew the body abou 1/4 turn) is much more effective at cutting parasitic drain; 100%
Good to see you back on Glenn!
