RFXCom Network Support

Feature Requests

Hi,

One of the products that was offered from RFXCom was the RFXLan device. It was essentially an RFXCom with a LAN connection.

It would be great if Home-Assistant could communicate with a remote RFXCom device, not only for network convenience, but also to permit the locating of the device in a more suitable place for the antenna to work effectively.

Whilst it could be bodged with ser2net, a more elegant solution would be to have the home-assistant hub communicate over TCPIP as well as the native USB/Serial. Ser2net and RFXLans work with the following settings in Domoticz and maybe other HA platforms…

echo “1001:raw:15:/dev/ttyUSB0:38400,NONE,1STOPBIT,8DATABITS” > /etc/ser2net.conf

Hi There

Did you get a response or find out about this, I have my RFXtrx setup using ser2net on a pi zerow and my domoticz setup can connect on 192.168.x.x:10001

I cannot find a way to get hass.io to connect over lan

3

still no solution?
I can’t connect to my rfxcom over lan , with domitcz it worked perfect

With a rf-link it can be done

Example configuration.yaml entry

rflink:
host: 192.168.0.10
port: 1234

source: https://home-assistant.io/components/rflink/

I do not think anyone have tried to add support for it yet.

sorry to bump and old thread but i’m trying to set this up - at the same stage can get rfxmanager to connect via lan and it’s working however cannot get hass to connect to it: tried using socat to connect to port but doesn’t appear to be working, any one else got this setup?

tried:

socat pty,link=/dev/ttyRFX0,b38400,raw,echo=0 tcp:IPADDRESS:PORT

and added /dev/ttyRFX0 as device path in configuration.yaml

this is home-asstant.log

network support would solve this! i’m happy to assist where i can to get this implemented!

Hi

Did anyone get this to work ?

I’m currently migrating from homeseer to home assistant, and hoping someone had the rfxlan device working in the mean time. Would the socat or ser2net approach work with the RFXtrx integration? I was thinking that the old rfxlan and the newer usb rfxtrx protocols where the same, just using another transport layer.

Any alternative approach?

I have tried to use socat but only to allow remote management of protocols in RFXtrx without physical access to it. What I did, I made an extra docker container on HA server with attached RFXtrx where socat was running and used another machine with another socat where I run python script to switch RFXtrx protocol settings (not using stock Windows apps). So this is a reverse of what you want.

But that is workable replacement for RFXLan. For that idea you need to have a spare RPi with Powered USB HUB where you connect your RFXtrx. Such setup you can move around. I’ve made a few posts about RFXtrx setup and its replacement.
