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 […]
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 […]
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 […]
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 […]
SensorBox v0.16 available
A new version of my SensorBox code for Arduino is available for download. Some of the improvements are: Optimized code. A loop is created to upload data of the TinyTX sensors to Open.Sen.Se ChannelID’s are stored in EEPROM ChannelID’s configurable via Telnet Watchdog timer Use the code as an example to build your own. There […]
Arduino DIY – Software updates
At the moment I’m still working to improve the DomoticaBox, SensorBox, Wireless LCD Display software. Once I have a new complete matching set that is suitable for download, I will update the links on this site again. Some improvements are: Watchdog to auto reset in case of lockups Use EEPROM for storing Open.Sen.Se feedID’s for […]
RTC timesync to Arduino
I’ve added some new code to the wireless LCD Display and my Raspberry PI to set the time on the wireless LCD display correctly and regularly. The wireless LCD Display has a DS1307 RTC connected but it is not the most accurate so time will shift after a while. The Arduino time library has an […]
