RFXCOM KAKU switched are added but after reboot unavailable

I have an installation of homeassistant core
I have by USB connected RFXCOM rfxtrx integration
I added the next lines to the configuration.yaml

rfxtrx:
  device: /dev/serial/by-id/usb-RFXCOM_RFXtrx433_A1RTAML-if00-port0
  debug: true
  automatic_add: true

After clicking the bound physical switch on my remote the switch is added to the Devices and Entities. So far so good.
But after restarting HA the switched keep unavailable until a reclick the physical switch on my remote.
Regarding to the log the sensor and switch are again added.

How can I solve this issue. The switches should be available after reboot of HA or PI

Which home assistant version are you using?

I am using version 0.113.3

Two ways to solve this:

  1. Update to 0.115.2
  2. Check the event code of the device and explicitly add it to configuration.yaml

I don’t understand. Almost two years later, and this is still not fixed?
I’m running
Home Assistant 2022.7.1
Supervisor 2022.07.0
Operating System 8.2
Frontend 20220707.0 - latest

I found the event code of the device, but I don’t know the syntax for adding it in configuration.yaml…

Can confirm that it’s still not working. My covers are unavailable after restart of HA. I have to add them again with the Event Codes over and over…
