An updated version of Open Monitoring Distribution (OMD) is available at the Bananian site here. They've build it for the ARMv7 (BananaPi, Raspberry Pi 2 & 3, OrangePi). I've written a complete install manual for version 1.00 which should work for version 1.30 too. Just make sure you use Raspbian Jessie. The related Check_mk_agent files can [...]
Many people want to build a node to test their own TTN (The Things Network) gateway and build new use cases. It's not that hard to build a node when you know which components to buy. With this post I've collected some information which might save you time in getting the things together. Building a [...]
This post will describe how to build your own LoRaWAN gateway to connect to i.e. The Things Network or other IOT Networks. If you haven't heard about the LORA technology and TheThingsNetwork and you are interested in Internet of Things, do some googling ;-) You've probably found this article because you are looking for a [...]
I've upgraded my domotica setup with a Philips Hue. Before I switched the lights using a remote control or via Node-Red and using the cheap 433 Mhz wall outlet switches of Elro, Klik Aan/Klik Uit, Action, and so on. Since the install of the Hue I was missing the remote control to easily switch the [...]
Secure your Node-Red install of TheThingBox with a login dialog to prevent unauthorized access.
We are at the start of a worldwide roll-out of a global open crowdsourced Internet of Things data network. If you have any interest in IoT or want to be part of the beginning of something big, check out the page that explains all, The Things Network. In short the guys behind this build a wireless [...]
I'm a big fan of Evernote and sometimes I just go through my notes, notebooks and tags to clean things up. Sometimes I then just check Google to see if people have good suggestions related to what I'm doing. In this case, I came across a site called moh.io where you can connect some of [...]
Oled display connected via SPI to NodeMCU Development board containing ESP8266 (type 12) = the silver square and FTDI for easy USB connection. Finally I made some time to play a couple of hours with a new type of microcontroller that offers a lot of possibilities. Especially for Internet of Things purposes! I'm [...]
Writing SDCard images using my Macbook took way to long, up to half an hour to write one simple Raspberry Pi image to a SDCard. I just did what many instructions told me to do. You will probably recognize this command: dd if=/path/to/image/file.img of=/dev/disk3 bs=1m (where /dev/disk3 depends on your system). Then I came across [...]
Today the new Raspberry Pi 2 model B was announced. ARMv7 CPU with 1 Gb of memory. This made me search for OMD (Open Monitoring Distribution) for ARMv7 (Which can be found here). While searching I stumbled upon an update OMD 1.21 for ARMv6 which is the original Raspberry Pi. I have two Pi's running. [...]
