7.7. MDREMOTE

This MDREMOTE has been tested.

http://www.ultraleds.co.uk/mini-dimmer-with-rf-remote-control-12-or-24v-dc-12a-maximum.html

The RFXtrx433 can only transmit MDREMOTE commands.

Procedure to find the ID of the MDREMOTE:

In RFXmngr enable the X10 protocol and enable “Undec on”

Press a button on the MDREMOTE remote.

The undecoded message contains the ID in the 2

and 3

byte, for example:

------------------------------------------------

08030C0220AF6801D1

Packettype = UNDECODED RF Message

UNDECODED NEC:20AF6801D1

The 2 bytes after 20 is the MDREMOTE ID, in this example AF 68

8. Blyss commands

Some Blyss devices, like the Blyss motors, require a special command sequence number. To

simplify it; 0,1,2,3,4,0,1,…

This sequence number is normally created by the Blyss remote but now also by the RFXtrx433.

If you use a Blyss remote and the application (Domoticz, DomotiGa, Homeseer…) does not sync

with the received Blyss command you will see that you need to send multiple commands with the

RFXtrx433 before the Blyss device will respond.

For example,

The Blyss remote transmits with the sequence numbers 0,1,2

If the RFXtrx433 transmits now with sequence number 0 it will not be seen by the Blyss device as

a valid command and at the time the RFXtrx433 transmits the commands 1,2,3 the command will

be detected as valid when it receives the command with sequence number 3.

The same is true for the remote. If you transmit commands with the RFXtrx433 and after that with

a Blyss remote you need to transmit several commands with the remote before the Blyss device

responds.

I guess the same behaviour will show if you use multiple Blyss remotes.

9. How to find the dx.com RGB LED strip driver ID

Flash the RFXtrx433 with Type2 firmware to be able to receive the remote ID in RFXmngr.

In RFXmngr enable only the LightwaveRF (AD) protocol.

------------------------------------------------

0A140605FCC48B00010081

Packettype = Lighting5

subtype = RGB TRC02

Sequence nbr = 5

ID = FCC48B

Command = On

Signal level = 8

If necessary flash the RFXtrx433 back to Type1 if Type2 does not support devices you need. (See

chapter 2.2)
