Domoticz, InfluxDB, Grafana

Domoticz part 5: Grafana, InfluxDB, Telegraf – beautiful and easy graphs

Grafana is the answer to the nagging question we’be been asking ourselves over the years – how to quickly and nicely present our data gathered from devices. InfluxDB on the other hand is the database that is as easy and simple to use, thus making it an ideal candidate for this job. Let me show you how to quickly and easily put our data from domoticz and other devices to InfluxDB and then using Grafana – display in much more useful way than default domoticz…

Raspberry Pi 4 Top View

Raspberry Pi 4 – a surprise but also radical change in the project’s direction

The new Raspberry Pi 4 is a very interesting change in the direction of the original project. Why? I will summarize what we already know, right after the premiere: new CPU, with much more computing power – not because of the clock, but ARM cores in version A72. The execution process – 28nm, is perhaps not the newest (it has never been) and, as tests show – the current is the higher temperature of the plate, and clearly the warmer PMIC system than in RPi…

0.96″ OLED SSD1306 display and Raspberry Pi

[Update: 2019-03-30] Our reader, Paweł Kopacz, noticed that pip, setuptools and wheel are also needed Quick and visually compelling projects don’t come easy ? Naaah, just like last time – let’s get on a very nice and easy project – attaching display onto Raspberry Pi. As we were chating on the Malinowe Pi Group, Hubert Wu pointed me to a OLED 128×64 display, monochrome. With a quite decent resolution of 128×64 and based on OLED technology this is a nice 0.96 inch display. Well, my…

SMOG = Raspberry Pi B z SDS011

[UPDATED 03-02-2018] SMOG sensor – 2,5 and 10 micro meter particles

[Last changes]: 07-11-2017: Additional data from richer stations, Open-Smog Integration 20-12-2017: USB power control on Raspberry Pi 3, thanks to reader 02-03-2018: New API from GIOŚ Poland SMOG is common nowadays in big cities. Let’s put together a working, precise own SMOG sensor, first for the 2,5 and 10 μm size particles. There is one issue – the choices are many, but only few are reliable, precise and have affordable price. Finally – after a log searching, I’ve chosen Nova Fitness SDS011: precision is OK fan…

CCS811 & BME680 with Raspberry Pi 0 W

Measuring air quality using Bosch BME680 and AMS CCS811 – IAQ, TVOC, eCO2

Measurement of basic environmental data in our apartment – temperature and humidity is one of the most popular applications of commonly available sensors for Raspberry Pi (RPi), Orange Pi (OPi) and ESP8266. Then we added ability to measure the SMOG otuside and inside and today we will deal with two new and very interesting air quality sensors. CAUTION: Don’t forget the basics of safety – we will be dealing with hazardous substances – they might be not only poisonous but also flammable! The Bosh BME680 sensor This…

Domoticz part 8 – Stable instance of Domoticz, 24/7/365 mode – high availability at home

As a result, a both fresh and advanced user finds himself in a situation where the system – ceases to work at all, or requires frequent restarts, or worse causes quick degradation of the main storage device – which is often (micro) SD card. Is there a simple and effective solution to increase Domoticz’s availability on Raspberry Pi / Orange Pi? Sure there is! But first – before you begin – make a copy of your (micro)SD working used in domoticz instance on your Raspberry…

Power supply for Raspberry Pi, Orange Pi, ESP8266 – XBOX 360 PSU modification

Proper supply of power is a very important part of our SBC (Small Board Computers) projects. Power supplies with too low current efficiency, instability and lack of filtration – often lead to accidental resets, lack of sensor readings or simply unstable behavior of SBCs. One of the solution is to modify the power supply from Microsoft console – XBOX 360. WARNING: We will work with high currents and high voltage, which requires basic knowledge of electrical engineering. The author is not responsible for accidents and…
