Is a numerical value for the S meter or the Noise floor available?

When I go searching for noise for EME even 1 dB is important.  Is there a way to access a numerical value for the S meter or the noise floor? Either on the 6600M or the Iphone app.  I remember finding a value on the Iphone app but I can't seem to find it anymore and I don't see an S meter on my phone.  When I go around my home or my neighbors homes, turning off lights, unplugging wall warts and generally encouraging my neighbors to use only candles for illumination, it would be great to have a better estimate of the changes in noise level.

    The SmartSDR for windows client gives the actual S meter value in dbm.  Just click on the S meter reading to change to numeric value.  I dont think there is a switch for this on the (M) front panel.  That would be nice to have.  Not sure about SmartSDR for iOS.

    Thanks, I'll try that.  I also found the S meter and a numerical value on the Iphone app by turning off the small slice flag and selecting Show dBm value.

    It would be nice for us "Stand Alone" users who don't use SmartSDR on a PC to also have that type of option to select dbm or numeric value.

    I just wrote a quick-and-dirty program to have the radio send S-meter data to my Linux computer in real time. Gives me a constantly updating dBm value for all active slices. Looked after my needs, although it was part of a learning exercise to have my shack Linux computer control the radio.
