Monitoring Energy Produced by Solar panels

We installed our solar panels back in 2011. They are still performing well.

We have 13nr 215W solar panels in two arrays connected to Sunny Boy SMA 1200 and SMA 1700 inverters. The whole lot is read by a Generation Meter

Technology at that time wasn't as great as it is now and I can't find any way of being able to monitor how much energy is being produced at any point in time unless I go and stand next to the Meter.

Anyone have any ideas on any (wifi / bluetooth) product that is available that will allow me to monitor the performance of our panels?

Thanks - any advice welcome
