I finally found some time again to build some LoraWAN Arduino toys for TheThingsNetwork. Basically it’s just a temperature sensor measuring outdoor water temperature and sending it once in a couple of hours via TTN to my Node-Red install. I’ve used the RN2483 library from JP Meijers which works great. I use an Arduino Pro […]
OMD v1.30 available for Raspberry Pi (AR...
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 […]
Build (TTN) LoRaWan Node
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 […]
LoRaWan Gateway – DIY
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 […]
RF 433Mhz to MQTT Gateway
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 […]
Login for Node-Red on TheThingBox
Secure your Node-Red install of TheThingBox with a login dialog to prevent unauthorized access.
The Things Network – LoRaWAN
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 […]
Mohio – Visualize your Cloud
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 […]
MQTT Data display using ESP8266 and OLED...
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 talking about the ESP8266 which, at the time of introduction, was used often as a very cheap WIFI adapter for i.e. Arduino’s. The ESP8266 costs […]
