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…

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…

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…
