Power meter graphs with prometheus.io and nodemMCU

Wed, 05/25/2016 - 12:04

I want to track and graph everything, which includes power consumption in my flat. But checking and regularly values and writing them down in spreadsheet is tiresome. Then I found this guide and after some modifications I've managed to collect actual power consumption, send it to Prometheus and see graphs in Grafana.

Control LIFX with NodeMCU and range sensor

LIFX bulbs are great, but when you just need to turn them on, off or just change brightness, it can be not very comfortable, to do this simple task by app. So I decided to create much simpler way to do this. And then I came across NodeMCU, small development board similar to Arduino with integrated Wi-Fi, with cost of about $5.

Welcome to ra100's lab

I've finally done it, this is my blog. Since it's my job to create websites, it has come to creating my web.

I will write here, if I will at all, about various tech (IoT) gadgets which I have or will create with RaspberryPi, NodeMCU etc. Meanwhile I'll try to continue with something I've begun on http://spaceunicorn.sk, reviews of gadgets from kickstarter or indiegogo. I can not forget about cosplay (the "cos" part). And there will be also something inbetween or something completely different, but I'll try to keep it technical.

And now, welcome to my laboratory.
