Kerui D026 door / window sensor & RFXTRXe

Configuration
1

Have a Kerui D026 window sensor and RFXtrxe hub

Have followed the component setup at https://www.home-assistant.io/components/binary_sensor.rfxtrx/
X10 and lighting4 enabled

I see the code in the logs per setup above, however on HA restart, the codes keep changing

Extract from log after restart

Any tips on how to successfully add these sensors?

Hello,
I have the same problem, did you succeed?

Yes, have them working reliably. As far as i recall, watch the logs carefully and only do one thing at a time, i.e. open close and tamper. Copy code out for each item.

Have found them very reliable, even outdoors.

Hello,
thank you.
I detect my sensors well but I can not configure them, can you show me your configuration?
(No on / off)

sure, no problem

Thank you for the configuration, it’s the same that I put pretty much but it does not work.
Indeed I have a D025 with only the return of ON.

I will surely change for D026.

binary_sensor:
  platform: rfxtrx
  automatic_add: true
  devices:
    08200019d680700279:

Any news here?
I have a similar problem. My Kerui sensor is detected as a Security1 sensor like yours @sypeer.
And I’m only able to get it working as an rfxtrx.sensor. With all the states open/close/tamper status.
The downside is, that the sensors are only updated every 30 seconds… so there is no way to use that to immediately do something if the door is opened.
That’s where I need to get it working as a binary sensor.
So, like I said at the beginning, any news?

Might not be an ideal solution as it means buying more bits, but I am using the Sonoff RF Bridge

I have the sensors responding instantly. Also got it working with PIR Sensors

9

The d026 kerui are instantaneous with rfxtrx here as binary sensors

10

I still have not succeeded
Sorry

11

Well, my IDs I get look like this: “0820000786bee08269”
So as you might see its recognized as a Security1 (20) type device. The only “working” configs use a 0913… So they are of the type “lighting4” (13).
I guess that there might be a problem … But I’m just guessing at the moment.
RfxMngr also shows it as a Security1 type, btw.
And another info I’m using a RfxComXL … which also could be an issue.

I also struggled with the Kerui D026 device. Now working perfectly. What helped for me was the following:

In RFXcom (RFXtrx433E) I disbled the X10 protocol. Now the doorsensor is detected as described in the home-assistant documentation of the RFXtrx binary sensor documentation.

13

Im pretty new with the RFXCOM. Can you explain how to disable X10 on it? I will for sure try it.
Thanks for the help.

14

You need to plug the rfxtrx into your laptop and switch off x10

Thanks for the fast reply. Gonna dig into it today and post the outcome.

16

In addition to fergalom.

In RFXmanager you can check if your Kerui is detected correctly. If you trigger your sensor. In the debug window of RFXmanager you see that it is detected as a lightning4 device.

success…

Hi all.

Update. I have disabled X10 and saw on the RFXcom lighting 4 wasn’t enabled also. I enabled it. After went back to Home Assistant.
set the automatic on true and triggered the sensor.
Outcome was 3 codes. I tried all 3 codes in the below setup, and the 2nd was working. Now my sensors work all. i have 4 of them working fine. Thanks all for the support! HA is awesome :slight_smile:
