TellStick Tutorial

Mon Jan 20, 2014 9:28 am

I am looking to buy a TellStick (http://www.telldus.se/products/tellstick) to connect to some RF Plugs (Probably Nexa), but I can't find any good English tutorials. There seems to be a few German tutorials, but I don't want to rely on them, as obviously a Google Translate may not be perfect, and some commands may be wrong.

Has anyone used a TellStick? Do you know of a good tutorial?

Hi,

maybe you don't need a TellStick to achieve your goal? I Just succeeded in using a very cheap RF tranmistter <$2 from ebay to control some 433MHz RF outlets using rcswitch-pi. I wrote a small tutorial here.

Best regards

I have looked into using an RF Transmitter, but I don't know how to connect things to the GPIO pins, and from what I have seen, they seem to be less reliable.

How good is the range of what you created, can it control more than one socket?

The tutorial has instructions on how to connect it to your gpio pins.
The module itself has very limited range <1m, but if you solder an antenna of 17.3cm to the hole labeled antenna on the transmitter I have no problem controlling an outlet in our bedroom from our Livingroom >8m through two closed doors.
Until now I have 100% succesrate controlling 3 different outlets, they never fail to react to a command.

I saw, but I don't actually know what you do. Can I connect the transmitter directly into the pins, or do I need wires? Do I need to solder anything? I have zero electronics knowledge. I read in other tutorials, that I may need a resistor etc. as well?

Would you recommend this method over the USB method, even for a noob?

The only thing you need to solder is the antenna cable to the small hole on the transmitter board. When connecting the board to your Raspberry Pi I would recommend using a set of female jumper cables. You can get them on ebay here. It would be a shame to solder something directly to the pins of the Raspberry Pi. Whether I would recommend this to a newbie or not depends on the person, but I would guess that when you ventured into the world of Raspberry Pi you must posses some interest in tinkering around with software and hardware :-)
I was looking at TellStick myself a year ago, but I like to keep it as simple and cheap as possible. Here in Denmark they are kind of hard to come by and they cost about $80 compared to the ebay RF transmitter modules pricetag of less than $2.

Okay, the TellStick is out of stock everywhere in the UK. So I think I may go down your method instead. It's definitely cheaper!

So just to be clear, if I buy an RF Transmitter I connect it to the Pi with a jumper cable? How does that actually attach to the Pi and transmitter if I don't need to solder it? Will I need a breadboard or anything?

Also, I plan to use a webserver to control it. Can I run the commands to control the switches in Python?
