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 [...]

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 [...]
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 [...]
I’ve been working on replacing the 433Mhz cheap transmitters (send only) by the RFM12b 868 Mhz Transceivers (send & receive) by using the RF12 library from jeelib. Things are working now, but it’s quite a bunch of work to convert all devices ;-). Also I’m very happy with the Attiny84 microcontrollers which allow some low [...]
I needed a solution to check every x-minutes if my IP camera is still online. I use the Pushingbox.com service to send a notification when a certain host is not available. Checkout Pushingbox.com to see which kinds of notification services they offer. At least a notification to email and Prowl! is possible. I've combined the [...]

I found the article below in which especially Pushingbox.com took my interest. Pushingbox is an online service which you can trigger from an Arduino microcontroller very easy. [...]
Since we've bought a bunch of solar panels on our roof, I'm building an electricity monitoring device based on the Arduino microcontroller. It's running for a while, monitoring solar power generation but now it can also read the Smart energy Meter which we got from the energy company. So currently it reads and/or calculates the [...]
