Pingback: SNMP Environmental Monitoring using ESP8266-based Sensors | Big Dan the Blogging Man
Have you done any work with Pascal and your weather station. I would like to write one for the raspberry and interface it to a website I have created using b4j
No, once I got wview up and running, I was happy with what I have. I have looked at the wview SQLite db. It is pretty straight forward and would be easy to interrogate. Free Pascal has an SQLlite interface. I have not used it yet, but all indications are it would be straight forward to extract wview data using a pascal program.
I’m trying to wrap up a long-winded hardware project. Once it is done, I’m actually looking at a project that uses Pascal and SQLite. Perhaps I’ll post an entry on getting the two to work together.
Have thought of the same idea with sqlite. Only thoughts were having two programs using the same database might cause errors. Will have a play and see what happens.
