[smartics : respond!]

After finally getting some frontend and visualizations done, I would not want to stop there. The logical next step in my opinion is to invest a little bit into the responsiveness of the application. Especially since an app that has a browser fontend is going to be opened on a mobile some time. In the…

[smartics : d3]

Where to start? Besides work and being sick, I got some d3 visualizations done over the last weekend and follow-up nights. What's my take? I thought it will be more complicated in general, but less complicated for myself. So all in all it was quite some effort to get some specifics with axes, scaling and…

To apply some smart logic for getting excess energy into the car I need to set some data on the charger. Like I wrote last time, since I own an go-e charger I will build a service to access its API. I will keep it simple and just add methods to read the chargers current…

[smartics : scheduler]

Today I want to follow up on my post about metering data. I already mentioned that I'm going for three similar but a little different data batches. The queries to get the data will be triggered at different times: MeteringDataSec will be triggered every five seconds, MeteringDataMin is triggered every five minutes and MeteringDataDay is…

I showed in the post a few days ago how to access inverter data [1.], now it's time to query the current values for a day. A word of caution though: all code I write about in these posts is supposed to run in the environment it was meant for. It should work, but I…

[smartics : inverter]

Before I bore you with statistics in the next post, I'll do so with a little intro into the application and code: There are already plenty of pages on how to setup a simple Java web application [1.]. Therefore, I'm just going to summarize what I will be dealing with and a bit of background…
