Rfxtrx ID & Unit code

Configuration
1

I have a built in lighting2 AC (Klik Aan klik uit) switch built in to an outlet.
In domoticz this unit has
ID
0010203
And unit code
5

I was wondering how this could be translated to the device codes home assistant uses? I could train a new code in the switch but i really don’t want to open the wall :slight_smile:

Good question, I’d like to know as well!

Enable auto add for rfxtrx switch:

switch:
  platform: rfxtrx
  automatic_add: True

Push your switch and it you shold be auto added to HA.

More information: https://home-assistant.io/components/switch.rfxtrx/

i’m sorry. it called it a switch, but technically it’s a receiver.
The receiver itself doens’t emit a signal it only receives it and switches on the light.
so the auto add doenst work with these…

You can ‘learn’ it up to six different remote codes.
But i only programmed one.

5

Ok, do you have remote control or how do you control it to day?

6

i used to control it with domoticz.
I added a device in domoticz with the ID and unit ID in my first post and paired it with that code.

7

Ok, then you are probably not able to trigger it from domoticz and lissen for the signal in HA at the same time?

8

nope, because i only have one rfxcom transceiver.

9

I see.
Then i do not know any easy way to fix your problem.

It should be possible to convert your id to the one used in HA.
A good starting point is: https://github.com/Danielhiversen/pyRFXtrx/blob/master/RFXtrx/lowlevel.py#L439

Ok, i wil try i can find something out. (not to hopefull as my programming skills are really basic).

for reference, this a comparisson between the domoticz ID’s and unitcodes and the home-assistant ones for the remote codes i receivced:

**Remote:**
Domoticz:                     0BCF2A2 1
HomeAssistant:                0b11003b00bcf2a201010f60
Domoticz:                     0BCF2A2 2
HomeAssistant:                0b11003e00bcf2a202010f60
Domoticz:                     0BCF2A2 3
HomeAssistant:                0b11003f00bcf2a203010f60

**Motion sensor:**
Domoticz:                     0B4C65E 10
HomeAssistant:                0b11002f00b4c65e0a010f50

Could it be this?
0BCF2A2 1 (domotciz)
0b11003b00bcf2a201010f60 (homeassistant)

prefix:  0b11003b0
deviceid: 0bcf2a2
unit id: 01
affix: 0f60

is the prefix and affix devicetype dependend?

11

Prefix:
0b is the length of the datapacket
11 means Lighting2
00 means subtype AC

self.packetlength = data[0] self.packettype = data[1] self.subtype = data[2] self.seqnbr = data[3] self.id1 = data[4] self.id2 = data[5] self.id3 = data[6] self.id4 = data[7] self.id_combined = (self.id1 << 24) + (self.id2 << 16) \ + (self.id3 << 8) + self.id4 self.unitcode = data[8] self.cmnd = data[9] self.level = data[10] self.rssi_byte = data[11]

So you can try to add:

0b11003b001020305010f60

That worked! I added a zero somewhere but it works! Thank you!

I am also using a RFXtrx433E with some KaKu plugs i have lying, besides my Z-Wave stuff.

I have learned the outlets the code from the remote and that code is picked up by HASS so i can control the plugs with HASS and/or remote. However, my remote has only 3 groups. But what if i want to add more plugs? Does anyone have a jinja template code to generate a random ID? I imagine that when adding a randomly created code and pressing ‘on’ when the outlet is in pairing mode, it will learn that code and we’re done.

I looked at the ‘self.’ part above, but can’t figure out completely how the message is set-up. The three switches that were auto-added from my remote are like this:
switch.0b11000500bc0cfe01010f70 switch.0b11000600bc0cfe02010f70 switch.0b11000700bc0cfe03010f70

I was thinking about a template like this:
0b11000{{ range(0,700) | random | int }}bc0cfe0{{ range(0,10) | random | int }}010f70
and it works! when creating a switch with the output code from it and then pressing the ‘on’ button in the GUI when the outlet is in learning mode. But i don’t think it is random enough, what do you think?

Sorry to resurrect an ancient thread but I have a dimmer switch with no remote. The normal “switch” template in the docs doesn’t work - and I can’t find one for a “light” - can you help?

This is literally the only reason my Vera is still about. Might just bite the bullet and put £300 worth of Hue GU10s in here just to not use 433 :wink:
