My device is remotely located and connected to a 4g modem to do the sending of data. I have been using the emoncms service as a platform to get the logged data out of the device into a web based platform. Running the Emoncms service at "post Interval = 1800sec , Frequency = 6 " ( i.e 1x 30min post with 5min incremental data ) .
The data usage has been exceptionally high at 30 MB per day and i cannot see why as i would presume the "payload to be a few Bytes - ( only 15 values ). The data usage from my ISP comes at a price and i am trying to keep this to a minimum. Ive also tested my data usage with the EmonCMS web server turned off , Updates on Iotawatt set to None , and there still seems to be a minor leak of ( 150KB/hour ).
So , 2 issues in 1 post really. A slow puncture and a very fast one with EmonCMS enabled. Please advise solution Bob.
