Classic Data Usage

Has anyone figured out just how much data a classic uses when talking to the mymidnite server? Our only available internet is through cellular providers, data going at $13/Gb. I guess the exchange is a bit more with the new test site having a higher update frequency.
a: 18 x 300W Conergy, 3 x Classic 150, 1 x Victron MultiPlus 24V / 5kW, 6 x Victron AGM 220Ah
b: 3 x 150W, 1 x Brat, 4 x Deka AGM 105Ah
c: 84 x Munchen 300W, Lorentz PS21k2 Controller, Lorentz PS21k2 submersible pump

Yeah I have these figures somewhere in my design documents but I keep losing track of them. I'll see if I can dig them up. The latest Alpha firmware uses substantially less than the older firmware even with the increased polling time. The polling time will also get dialed back a bit for general release to reduce the load on the server.

The Classic uses approximately 2,019 bytes every time it dumps data to the mymidnite server. This is approximate because there are mitigating factors like additional HTTP headers added by inter-router hops, packet splitting and reassembly, bad connections, etc. This number includes all the TCP traffic such as SYN, ACK and FIN packets as well.

Thanks. How often does it send this?

On the test server it's once every 5 minutes or so, when we go to production it will be more like 10-15 minutes.

So it's the server determining when it pulls data, not the classic pushing at a set interval?

When released for production the Classic will try to log in to the server every 5-10 minutes, the server will either let it continue to log in or deny the log in  based on its own configuration.  Only after a successful login will the Classic dump its data to the server.
