Hi – I have just put a load of LWRF devices in y house and was about to buy the Link box.
Range is a worry as its a big house – so this got me thinking – is it possible to have multiple RFXCom or RFXLan devices on one RPi/Domoticz setup? so I could position them around the house (I have Cat6 dotted around) to ensure I don’t have range issues?
Yes, you can connect multiple RFXtrx433E to Domoticz.
To connect a remote RFXtrx433E you can use an USB converter over Cat6 or use a RaspberryPI with ser2net installed to access the RFXtrx433E over LAN.
ser2net installation procedure
Disable Serial Console
sudo nano /etc/inittab
insert a # sign in front of this line:
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
sudo nano /boot/cmdline.txt
delete these 2 fields: console=ttyAMA0,115200 kgdboc=ttyAMA0,115200
sudo apt-get install ser2net
sudo nano /etc/ser2net.conf
10001:raw:0:/dev/ttyUSB0:38400 8DATABITS NONE 1STOPBIT
10002:raw:0:/dev/ttyUSB1:38400 8DATABITS NONE 1STOPBIT
sudo /etc/init.d/ser2net restart
sudo nano /etc/rc.local
add the next line before exit o :
Easier and cheaper would be to get a better aerial. Search the domoticz forum for ones that will work. My range is greater than 100m using a better aerial.
