Domoticz part. 7: Heating your house with Z-Wave

We do know how to install domoticz. But how easy is to control heating in your house/flat? After full season of testing radiator control – I can recommend a very interesting and useful heating control system that you can setup in your home or apartment. All just by means of adding radiator thermostats with Z-Wave radio. What will you need? Software Up to date Domoticz installed on PC, Raspberry Pi, Orange Pi or other – with Linux operating system Hardware One free USB 2.0 or…

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…

Tracking gliders, airplanes, helicopters and baloons, part 3 – FLARM

We already know how to track airplanes using DVB-T USB dongle and Orange Pi or Raspberry Pi. Let’s move on to a new system that allows tracking of light aircrafts: gliders helicopters baloons smaller airplanes FLARM – is a collision avoidance system for light aircrafts, popularized and approved by EASA, gaining traction, used mainly on gliders in Poland and Europe. We’re not going to use it to avoid collision – but to receive position and track light aircrafts – so we can share them on the…

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!] This is a modification of: https://bitbucket.org/MattHawkinsUK/rpispy-misc/raw/master/python/bme280.py, 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 program will update Domoticz via JSON.

SMOG = Raspberry Pi B z SDS011

[UPDATED 05-04-2017] SMOG sensor – 2,5 and 10 micro meter particles

[Last changes: Additional data from richer stations, Open-Smog Integration] 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 included ability to mount a small tube to access external air very realiable UART with USB converter included…

Tracking airplanes with ADS-B & MLAT revisted- building a better and cheaper reciever for Flightradar 24 and Flightaware

[Update 2017-08-22 – Sharing data with friendly radars] A lot has changed since the last entry about tracking the aircraft using ADS-B messages. There are new options for data sharing, greatly simplified installation procedure and – optionally new equipment. This allows you to build a new receiver with an emphasis on simplicity, yet lower cost of purchase and maintenance with new feature (MLAT). Moreover, in addition to the aircraft you can now track other aircraft – i.e. meteorological balloons! I call that progress! What will…

Rain/Snow/Water detection system

Domoticz part 6: Water/Rain/Snow/ sensor FC-37 using ESPEasy (digital)

We return today to the simple and quick solutions! The weather station or irrigation/sprinkler system – can’t operate without proper detection of rain, water or even snow. Let’s use the FC-37 sensor (also know as YL-38 or MH-RD, or just similar to the picture) What will you need? rain sensor type FC-37/MH-RD (rain drop/snow sensor) – must come with D0 pin, price around $0.50 to $1.50 ESPEasy working on ESP8266 from the previous entries Installation and configuration The sensor must be connected to the power supply + 3.3V (3V)…

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 B+ with Neoway GSM M590 module

Raspberry Pi and GSM network- sending SMS, connecting to the Internet (IoT)

This time I’m going to connect to our Raspberry Pi a GSM module. Why? Internet of Things, in short IoT, as it was noted at Krakow’s PLNOG17  by Marcin Aronowski involves and depends on the network which should be easily accessible, and the very essence of IoT is the energy efficiency. Perhaps, he said, 3G will go away but 2G but will still remain. And we do not huge pipes – just enough bandwidth. 2G connection is still the cheapest in the implementation (also due…
