Originally posted by **garyh2626** November 3, 2022 Thanks for all the work on RTLAMR, i am successfully reading both my electric and gas meter. Now I am trying to get this working with a recently installed Water module. RTLAMR is receiving my meter since the endpoint number matches the number on my meter. Output in json mode: Protocol: 30, EndpointType: 171, Endpoint: MyMeterID. Consumption: 126 | Normal text mode Protocol: 0x1E, EndpointType: 0xAB all other remain the same The problem is consumption only shows first 3 number of the reading and missing the last 5 numbers including decimal point. 126 where the meter actually reads 12652.111

This is not really an issue. Found previous water bill and confirmed the water company only charge for usage per CCF, 100 cubic feet = 748 gallons. From bill: previous reading 121, current reading: 125, units: 4, measurement CCF. This explains transmitting only significant digits for billing.
