Nexa LMLT-711 Push-Button

Hi!
I’m trying to use my two push buttons for my door bells with my Vera and RFX. I want to trigger something, be it sending a Prowl, turning on a light or reading something in Swedish on one or all of my Sonos devices, when either buttons are pressed. In my GUI the RFX have taken the signal but I can’t figure out how do anything useful at all. Please help, reading some threads haven’t helped me either.

The bell itself works fine with the buttons by the way.

Hi, I have a couple of these also and what you need to do is ti use the scene number 100 to trigger your scene.
I use PLEG to trigger my actions but you get the idea right?

I’m clearly not getting everything. The scene is now working, and if I press the Group On button it works fine. So I reckon my problem is with the initial signal from the Nexa. Would it be possible to write an explanation from the start…
Ain’t my proudest moment. ;D

You did get a device like the one in my picture created automatically when pressing your doorbell button right?

Then all you need to do to trigger your scene is to use scene number 100 from this device as a trigger.

If you on the other hand want to make the doorbell make some sound from your Vera you will need to put the doorbell in learning mode and then press the Group ON button in Vera. (It is possible to have both scenarios set up for the same Vera device without them interfering with each other).

If you can not get it to work we need to start from checking what version you are using of the RFXtrx433 plugin and your Vera Firmware and try to get some logfiles.

Hello,
I have the same problem, I have a Nexa DoorBell and it has a 230V powered chime.
RFXtrx identifies it as X10ChaconRemote. What i want to achieve: Every time someone rings the doorbell, VeraAlerts will send me an email containing a snapshot from the entrance camera. Like this: {Subject=Someone is at the front door} {Picture(172)} {To=xxx@somedomain.com}.

I got it working for a brief moment without the attached picture, only a “Unit notification”, after that no notifications at all, no matter what i choose. I also do not know where to put the code {Subject=Someone is at the front door} {Picture(172)} {To=xxx@somedomain.com}
Thank you in advance,
/Mike

I have got my Nexa LMLT-711 working with the LML-710 doorbell. I have 1 X10ChaconRemote in my UI5, from where I can ring the doorbell after I paired it with the LML-710. At the moment, the push button and the UI5 device have the same ringtone. I would like to add another X10ChaconRemote device to my UI5, to be able to have another ringtone, so I could trigger 2 different ringtones to trigger from Vera.
Is that possible and how ?

In theory you could just use “device_file” and “device_type” from the one you have and create another from APPS → Develop Apps → Create device
Point it to the correct “Parent device”.

Not sure what else you need to enter in order to get it working.

I thought about that, but my thought was that it would probably send the same signal as the first device, so the doorbell could not differentiate between the 2 devices. I might have overthought that one, I’ll give it a try.

Maybe you need to come up with another “altid” for you device here is the altid of my 2 devices for reference:

RC/L2.0/09735EA

RC/L2.0/096F852

Yes I think that could work. Good idea. That could / should get around the 2 different frequencies.
