RFLink

RFLink R48 is pre-installed on the gateway.

RFLink Protocol describe what is detected.

Connect gateway via OpenBSD.

doas cu -l cuaU0 -s 57600

Connected to /dev/cuaU0 (speed 57600)
20;00;Nodo RadioFrequencyLink - RFLink Gateway V1.1 - R48;
20;01;MiLight=ON;

The gateway expects CR/LF after every line, but cu only interpret Enter as CR.

CTRL-M - CR
CTRL-J - LF

So to send commands back directly with CR/LF termination you need to add an extra LF.

10;PING;<Enter><CTRL-J>
20;04;PONG;

You should also be able to use e.g. minicom or screen.

Weather Station(s)

Ambient Weather WS-1173 and its outdoor sensor WH2F seems to be picked up as.

20;2C;FineOffset;ID=0014;TEMP=00ca;HUM=49;

This means

0xCA = 202 = 20.2 C
49% relative humidity

Buy more here.

Another weather station seems to be from Alecto.

20;26;AlectoV3;ID=3014;TEMP=80b7;HUM=48;BAT=OK;

That one report -18.3. Inside a freezer?

And yet another Xiron/Auriol.

20;7B;Xiron;ID=1401;TEMP=0085;HUM=53;BAT=OK;

Custom ATtiny84 with DHT22

Custom firmware from NDSensors

Controlling Telldus Switches

I tried to control the switches from the telldus web ui. Then I got the following …

# kök
20;15;NewKaku;ID=004a4b52;SWITCH=1;CMD=ON;
20;16;NewKaku;ID=004a4b52;SWITCH=1;CMD=OFF;

# mat
20;18;NewKaku;ID=02a4beb2;SWITCH=1;CMD=OFF;
20;19;NewKaku;ID=02a4beb2;SWITCH=1;CMD=ON;

# tv
20;1C;NewKaku;ID=03cdb752;SWITCH=1;CMD=ON;
20;1D;NewKaku;ID=03cdb752;SWITCH=1;CMD=OFF;

So from this I could get the ID for each device.

So to control from RFLink i could do the following.

10;NewKaku;004a4b52;1;ON;<Enter><CTRL-J>
20;21;OK;

And

10;NewKaku;004a4b52;1;OFF;<Enter><CTRL-J>
20;23;OK;

Works fine!
