Rfxtrx Nexa doorbell Group On command

Configuration
1

I have a Nexa 433 MHz door bell (LML-710) that is triggered by 2 separate remotes (LMLT-711). I have the automatic add pick up the device but whatever I do it never change state. It just sits there as “off”.

I already have it as fire_event: true but it doesn’t change anything.

I have tried to configure it as a switch, sensor and binary_sensor with no change.

This is how it’s currently added.

binary_sensor:

  • platform: rfxtrx
    automatic_add: false
    devices:
    0b1100010152033201040f60:
    name: Entrance
    fire_event: true
    off_delay:
    seconds: 10
    command_on: 0x04

What I’m after is to have it register when someone rings the door and possibly use it in some automation such as notifying my phone.

I know, coming from Domoticz, that the remote sends a “Group On” command so I tried to add command_on: 0x04 as it is a lightning 2 device. No change, still just sits there in “off” state completely useless.

Hi, i have a similar issue. Using a Nexa Doorbell that sends the “group on” command and the device that is added to home assistant only shows on/off.

Have you had any luck with your setup?

No really, at least not as I intended.
I copy pasted the code from someone else and at least I can get an automation to send a notification to my phone and also turn the switch on, wait 5 seconds and then turn off. That way the switch will display when it was last triggered.

But the switch itself doesn’t do anything or react to anything without the automation. Maybe it’s by design but they are not working like I was used to from Domoticz.
