Newbie - hardware question

Good evening,

I’m waving my white flag of surrender!

I can get nothing out of the Sharky 775 meter despite trying different addresses, page numbers etc. The green LED on the USB board is happily flashing but all I get is

DEBUG    MBUS       Decoded MBUS data: None

I’m also still struggling to get anything out of the SDM120 as per the other thread that I gatecrashed!

Any help would be gratefully received

Thank you
