Hi @Gary Pacey

A 'per-record' figure is a little academic, as you don't get a choice. VRM takes it all.

There's some discussion about it in the CCGX manual, see Section 5.3:

Depends on your log interval and devices being monitored, but the 25Mb/month mentioned there is about what I experience with per-minute sampling on a simplish system.

Please note that although the amount of data is small, I've been bitten by my mobile internet provider...they often charge a minimum amount of data per connection, and this can lead to more data use on the bill than you actually use. not nice when you are roaming and on high tariff

So..beware of the small print in the data-rules of your internet connection..
