Multiple rfraw payloads

Third party integrations
1

At home we have several gas fireplaces (Bellfires/Barbas).
With a Sonoff RFbridge, Tasmota and Portisch I found the rfraw codes to turn them on and off.

  - platform: mqtt
    name: "Fireplace downstairs"
    command_topic: "cmnd/tasmota_rf/Backlog"
    qos: 1
    payload_on: 'rfraw AA B0 plus payload'
    payload_off: 'rfraw AA B0 minus payload'

But, to light the fireplace they need several times (8* minimum) the on/plus payload in a row.
Is there a way to do this?

This works, when I do 4* on/off in a row, but I’m looking for a better solution.

  - platform: mqtt
    name: "Fireplace starting"
    command_topic: "cmnd/tasmota_rf/Backlog"
    qos: 1
    payload_on: 'rfraw AA B0 plus payload'
    payload_off: 'rfraw AA B0 plus payload'

Solved by firing the on command 8 times with a script/automation.
