EKM Metering

Is the EKM-Push Communication System and the EKM Dash (dashkey) the only things I need to read the meter (remotely) from inside my home (I really don't need to read it from anywhere else) with the 3/4" Pulse Output Gas Meter - PGM-075 ? Do I really need the EKM Omnimeter Pulse v.4 – Pulse Count...
