RF transmitter for 868.3Mhz (Niko EasyWave)

Hi,

I had this idea of connecting a RF transmitter (capable of sending on 868.3Mhz) to take over the remote control of my home's windows blinds. Currently this is done by individual RF controllers from Niko, called Easywave systems.

Programming Niko's pulses and possible encryption/algorithms aside my first hurdle is finding compatible RF transmitters for the Pi. I found two boards who have the capabilities but have no clue if they are compatible with the Pi:

Would this even be possible on the Pi ?
thanks for your input folks.

I've no idea if it will be compatible with Niko Easywave, but you receive a USB<->868MHz RF dongle as part of the TI Chronos dev kit:

This works perfectly with the RPi with a simple /dev/ttyACM0 interface:

And if you can't get it to work with Niko, there's lot's of other interesting stuff to play with:

I suggest you look at Ciseco's http://shop.ciseco.co.uk/ XFR which is a 868Mhz transceiver (TI C1110 chip) they are fairly cheap at around £10. They can be reprogrammed because it contains on an onboard MCU. I've been using these for my custom Alarm project http://jas-hacks.blogspot.co.uk/2012/04/nano-sl5-alarm-panel.html. You can easily interface to the Pi using the onboard Uart interfaces as I have done.

Hi,

I know this is an old post but did you anyhow succeeded to control your Nikobus with the Raspberry Pi?
