I have a Mango installation on setup on a server which is being fed data over HTTP by a script running on a RasPi (reading from modbus).
The Mango installation has a HTTP receiver data source configured with around 30 data points, all running perfectly fine. :-)
However, I have a problem with the way Mango manages its timestamps. The time-stamp it uses is the actual time at which the POST message was received. This however, poses a problem as the data that was read over modbus might be older (due to network delays, or caching, or network down time etc) than the time it actually reaches Mango.
I tried using this: "http://192.168.1.xx:8080/httpds?__time=yyyyMMddHHmmss&item1=val1&item2=val2" and sent ```
P.S.: I tried installing Mango on RasPi but it had performance issues, couldn't read modbus as fast as the python script I wrote. However, the HTTP Publisher was a blessing with its auto-caching etc. :wink:
