How to emulate 433mhz 1ByOne door chime press from HA

Configuration
1

I have RFXTRX433E and a 1ByOne door chime that uses SelectPlus protocol. I have a rfxtrx sensor set up as follows:

- platform: rfxtrx
  automatic_add: false
  devices:
    07160200009f5940:
      name: door chime
      data_type:
      - Sound
      fire_event: true

this is working as expected, i.e. when someone presses the doorbell HA gets signal_received event, which i use in automation to send pushbullet notification to my phone.

Now, how do i emulate the press of doorbell from HA?
i created following switch in HA:

- platform: rfxtrx
  automatic_add: false
  devices:
    07160200009f5940:
      name: door chime
      fire_event: true

But, when i press the switch, i get the following notification:

Failed to call service switch/turn_on. ‘RfxTrxDevice’ object has no attribute ‘send_on’

i a different topic i read that X10 protocol should be disabled in RfxTrx in order the switch to work, however, mine is disabled, but switch still doesn’t work.

Any idea how do i send RF signal to door chime using HA?

thank you
