We have a set of dataloggers that are monitoring AC & DC Power sources via digital and analog inputs. We need a developer to build a database and interface system to recevie/get the data from the loggers using TCP &/or gprs - the loggers are capable of both which is why we picked them. Preference is TCP with GPRS as a backup. The dataloggers are from company KingPigeon and unit is an S275 - all docs/manuals attached. Data upload frequency every minute so we can see (almost) realtime what is happening with the power and react by activating a relay which is also connected to the S275 unit so the interface must be able to be bi-directional. I will make an s275 fully available on a fixed ip address for the project. We have hosted databases already - either MYSQL or MSSQL, you can choose whichever platform to use. The Developer MUST have done something like this before. Thanks in advance, Mark
