ESP8622 z wyświetlaczem SSD1306 (OLED) DHT22, BH1750 pod ESPEasy

Domoticz part 3.1: ESP Easy on ESP8266 – remote and local OLED display with temperature, humidity, light – weather station

Previously we played around the SSD1306 OLED display as side display for Raspberry Pi. The author of ESP Easy – Richard ten Klooster ( – recently updated his project to include new sensors, so today we will update our DHT22 enabled remote sensor for Domoticz with display and light metering. Our weather station will get a remote display. I’ve created such bundle of sensors to allow both temperature and humidity measurement small shack for chopped wood but also to light the way to it after…

Raspberry PI + BME280

BME280 in Domoticz – updating the sensor data via Python

[Update: 30.07.2017 – as of now – latest stable domoticz version supports BME280, so this is now obsolete! The Hardware menu has now I2C Sensors and BME280 is present in submenu] This is a modification of:, which after you change the IP address and port of Domoticz in ip_domoticz, and creating dummy sensor in Domoticz – “Temp+Humi+Baro” – and then changing the IDX to it’s value in: idx_dummy_bme280 – will update the sensor with the same data as you can see while running the program. This…

DS18b20 with RPi - connections

Domoticz part 4: connecting the DS18b20 thermometer

Temperature readout is one of the first sensor we add to domoticz. It’s a very simple task and allows to connect multiple thermometers via the 1-wire bus. 1-wire means that thermometer has a single data wire, on top of VCC and GND. This wire is used to send back data to 1-wire controller and then it gets verified. What will you need? Hardware: thermometer DS18B20 (Dallas) – comes in variety of housings – usually it’s a chip with 3 pins. It’s good to measure from…

ESP8266 on NodeMCU Amica Board with DHT22 sensor and battery power

Domoticz part 3: ESP Easy – quick and easy sensor for weather station using ESP8266

ESP8266 has become so popular that a beginner can choose from multitude of projects/firmwares and then – just start using them. Advanced IoT adopters will praise it’s quick implementation and stability. Today we will check out the Richard Ten Klooster’s project ESPEasy – Basically ESPEasy is a firmware that can be flashed onto ESP8266 – preferably ESP-12E or ESP-12F and right after boot – we can join it’s WiFi access point (AP) to configure it via web interface. No console needed. Then, it is…

Raspberry Pi B+, ds18b20, ESP8266

Domoticz part 2: WiFi remote thermometer for weather station, dual digit precision – it’s ESP8266 for beginners

Last time we installed Domoticz, and soon we will move to Z-Wave, but first – let’s take a look at fantastic little gadget: ESP8266 What is an ESP8266? ESP8266 (also called  ESP here) is a SoC – System on a Chip, which in our case is – CPU/RAM/FLASH with GPIO and WiFi interface – so another mini komputer with wireless interface. You can think of it as scaled down version of Raspberry Pi, less power hungry, but with own WLAN and a lot (minimum 2)…

Domoticz on PI with relay

Domoticz part 1: Relays, magnetic sensors, Wake-on-LAN and Z-Wave – Domoticz with Imperi Home serving your house

This entry was initially about single and simple purpose: how to quickly develop a solution that would open gate or garadge door by simulating the remote’s operation mode – pressing a button – but using smartphone, tablet, web browser, app. Domoticz is such an overkill and also blessing for such project – that it evolved into a lot of small sub-projects – more or less andvanced. Direct inspiration was another entry by colleague on  MalinowePi Facebook group – Roman Kubat, who showed ImperiHome. This application has great interface but…

Light effect for any device with Video output based on raspbmc or OpenELEC and RaspberryPi

“Good news, everyone!”. If you succeeded in creating light effect using the previous entry: you must’ve noticed that it’s limited to the content being played by raspbmc or OpenELEC. Luckily thanks to constant development by hyperion’s creator (tvdzwan) we’ve just got ability to use the effect with other devices that have video output the Usually modern STB, Blu-Ray player or amplituners sport a SCART output or the yellow colored ‘Video’ output. What is important – they allow both HDMI and Composite video outputs to…

Pi with Light Effect

Light effect for Raspberry Pi based media player – raspbmc or OpenELEC/LibreELEC

Raspberry Pi can be easily used as media player. We can choose from many variations, but the one I’d like to focus on is Raspbmc based on XBMC. Raspbmc with hyperion has ability to drive RGB LED strip or daisychain using Raspberry Pi. The important part is that it will lit the RGB LEDs accordingly to the screen borders in realtime. It’s used to make the visible part of the picture more vivid and extend it beyond the display, and it’s simply quite cool: So,…

SDR using Raspberry Pi: Tracking airplanes above our heads – recieving ADS-B data with visualization using DVB-T dongle

  Note: There’s a newer version of this entry – updated with latest tests, much easier to install: Last time I’ve shared with you the Raspberry Pi “computer for a buck”. Unless you’re are learning Python or playing Minecraft – or better – you’re already bored – I have a new thing fro you. It’s a very nice idea that you can use as your graduation or school project – and it’s all about tracking airplanes high in the sky. From hardware point – you will need a DVB-T/DAB USB dongle…
