GoAcccess Nginx Analysis
Few days ago, I installed GoAcccess which is an ( open source real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through your browser. ), to analyze my NGINX access logs.

Python Logging Benchmark
If you have a heavy logging application, you might want to take into consideration to use the %-format strings for logging. The Python logging module recommends to use the %-format . But I guess most of the developers will prefer the f-string format, which came with the Python 3.6 release, because it simply easier to read.

You can either spin up a web server on your ESP and pull the data or send data from your ESP to your Home Assistant. The…
Home Assistant - Smart Life components
Home Assistant unfortunately doesn’t support Smart Life components (yet) (e.g. Switches from Gosund , COOSA or Teckin ), but fortunately IFTTT works great with Smart Life components, which can be connected to Home Assistant. In my example, I will show you how to turn on/off lights by using Teckin Switches with help of IFTTT. The result in Home Assistant will like that:
ESP8266 Overview - Arduino IDE Setup
ESP8266 is a low cost (2-3$ in begin of 2019) WIFI microchip with a 80/160 MHz CPU, which will be used for a lot of DIY projects. If you are looking for more powerful microchip, or you need Bluetooth capability, check out the successor ESP32 . I bought the “D1 Mini” model of ESP8266 with 4MB flash (you can get them e.g. here ). Note: It is not the WeMos D1 Mini, but a copy of it. The PIN diagram…
