[eval : february]

In the last two weeks I did not invest that much time into programming but was vacationing in the Austrian Alps instead. Nice for me. Still, I am somewhat finished with an early historic view on metering data on a monthly level. Since I do not want to keep that to myself - especially due…

[smartics : routing]

This weekend I worked on showing historic data. To actually show anything but the current overview I had to get the menu in the application working first. For that I am using another library called react-router. I will quickly show how to include it in a react app that is already using bootstrap. First we…

[eval : charging smart]

Two posts ago, when showing how to do d3 charts, I mentioned that in the graphic presented smart charging was already visible in action. I will present another example from the last weekend where I had the chance to gather more data with the implemented algorithm. The inverter data summary is also updated and looks…

[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…

[smartics : react]

This weekend it was time to finally start on some frontend work. I'm staying with react and webpack as I wanted to get into those for quite some time now. Major other points I take into account are staying flexible and keeping the load on the raspberry pi low. I'm starting by showing how the…

[smartics : charging smart]

In German there is this saying - freely translated: 'firstly it will be different, and secondly than you think'. The translation might not fit it so well but in general the idea is that even when you know it will come differently, the outcome will quite often be even more different than predicted. This, of…

[plan : charging smart]

Let me introduce a first model of how I'll build a smart charging algorithm. I will have to add one or two new methods for accessing statistical data but besides that, I think I'm already well set. In short: let's take excess energy depending on the predicted use for the current times. Overriding to quickly…

[smartics : charger]

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…

[plan : smart charger]

After laying some ground work by gathering energy use and production systematically, it's finally time to build up some smartness. I want to use excess energy of PV panels efficiently to charge an electric car. Here I will show you what's the plan and needed beforehand. First, what's needed is a charger that offers a…
