Simple Ethernet Board with Register

Started by Klaus Kragelund October 29, 2013
Hi

For a home automation project, I need to control some devices via an ethernet connection.

I could use a raspberry pi, but I am looking for something simpler. In some cases I just need to set or clear a relay.

Do anyone know of a very simple board with an ethernet Phy on (possibly with a logic output), that can be used for this?

Perhaps something like a W5100 based board.

Regards

Klaus

Well, almost. Except it costs more than an entire Raspberry Pi board. I was looking for something in the neighborhood of 5-10USD. Like: https://www.olimex.com/Products/Modules/Ethernet/ENC28J60-H/ But with an output that could be set without the need for the action of an external microcontroller Cheers Klaus

This is 6USD with a board, but still needs an external controller (perhaps I need to accept that that's just how it is): http://www.geeetech.com/arduino-enc28j60-ethernet-module-p-263.html Cheers Klaus

Simpler than a Raspberry Pi is very difficult, counting price and time. I did this with an ebay ethernet module: http://panteltje.com/panteltje/pic/usa_pic/ I wrote both C code to interface to that chip, and PIC18 asm. But these days I would use the little Raspi Linux computer anytime, better, much more flexible (TCP UDP), and perhaps works out even cheaper. Just make a little 'shield' board for the Raspi with a relay on the GPIO pins. 2 relays, 10 relays... program in C.

This is just a pre-programmed micro-controller with interpreter.

So, you are talking about addressable node (or endpoint), which is outside the IP framework itself. Can't think of how it can be done without additional processing layer; namely, a microcontroller.

A USD6 micro, for example: PIC32MX675F512 has ethernet phy. You just need the connector. Full IP stack is free from microchip.

Looks nice. Ok, so if I do it the Rasperry way, what would be the easiest for someone who has only use Linux on a user level and never dug deep into the engine? I found the Webiopi nice: http://code.google.com/p/webiopi/ How do I get started, is it just some code in a nice GUI? ...and putting that code in whats simelar to "Startup" in windows, so when it boots it runs that code? Thanks Klaus

The reason I am looking for a simple (single device) is that this home automation is just something I would like to do when the kids and wife are asleep, so I am aiming for something that does not involve a lot of hardware, but rarther works out of the box Cheers Klaus

but it is simple ;)

several ENC28J60 boards on ebay for 3-4$, pair it with an avr and you can probably find some arduino code the will work with little modifications -Lasse
