Comcast will show me my total data usage at any point throughout each month, but this is mostly useless to me because I don't know which services (Netflix? Spotify? Email? Amazon?) are using the most data. I have heard of third-party firmware that can measure/log this usage, but it is unclear to me if any of them are compatible with the xfinity 1 modem/router/acess gateway or whatever they call it. It is hard for me to believe that Comcast can now limit my data usage without providing me the tools to know which services are consuming the most. I also don't trust their measurement.
