Home of FHEM
Description Fhem is a GPL'd perl server for house automation. It is used to automate some common tasks in the household like switching lamps / shutters / heating / etc. and to log events like temperature / humidity / power consumption. The program runs as a server, you can control it via web or smartphone frontends, telnet or TCP/IP directly. In order to use FHEM you'll need a 24/7 server (Fritz!Box, NAS, RPi, PC, MacMini, etc) with a perl interpreter and some attached hardware like the CUL, FHZ1300PC, etc. to access the actors and sensors.

RF24Network for Wireless Sensor Networking RF24Network is a network layer for Nordic nRF24L01+ radios running on Arduino-compatible hardware. It’s goal is to have an alternative to Xbee radios for communication between Arduino units. It provides a host address space and message routing for up to 6,000 nodes. The layer forms the background of a capable and scalable Wireless Sensor Network system. At the same time, it makes communication between even two nodes very simple. Today, I managed to get 17 nodes running on a single network. Open Automation English: The CometVisu is an interactive, realtime, web based visualization.

[Arduino] DIY (stupid and cheap) Plants Irrigator It’s a burning summer in Florence and I needed a solution to watering my little plants I have around the house. Of course I had a look at some shops for a ready solution, but where is the joy of experimenting with an arduino? First thing to do in this case is to know what you want, and where your project could drive you. It’s nice to fly high with ideas, but to make them affordable you have to take off first. So here we are with our project/tutorial: a time programmed irrigator which will water my plants for 1 minute, once a day, on alternate days.

Dreamscope Photo Filters Inceptionist Painting Salvia Art Deco Painting Mirage RF24Network: Network Layer for RF24 Radios This class implements an OSI Network Layer using nRF24L01(+) radios driven by the RF24 library. Purpose/Goal Create an alternative to ZigBee radios for Arduino communication. Xbees are excellent little radios, backed up by a mature and robust standard protocol stack. They are also expensive.

Getting Started with nRF24L01+ on Arduino Nordic’s nRF24L01+ 2.4GHz RF radios are a great way to communicate wirelessly between Arduino’s. They’re cheap, and powerful. Unfortunately, they can be a little daunting to beginners to get started. Mike Bostock December 27, 2014Mapping Every Path to the N.F.L. Playoffs December 20, 2014How Each Team Can Make the N.F.L.
