Ghost interrupt of rf433 switches triggers turn_off in homeassistant

Hello all,

I have configured a multisensor containing also an RF433 emitter receiver. This box is configured to manage a cover in the kitchen.

From time to time, about twice a day, the entire box disconnects from the WIFI without any understandable reason, for less than a minute, then reconnects.
The log in Homeasssistant looks like this:

As can be seen on the log, the entire list of switches and status goes to unavailable for a few seconds, and then back to available.
The problem is that when coming back online, all switches are set to OFF and send the 433 MHZ signal for going off, and dont come back on.

The esphome switches are programmed under ESPHOME as such:

esphome:
  name: basic_rf433_plugs
  platform: ESP8266

      if (id(plugA_Start).state) {
        // plug A is ON
        return true;
      } else if (id(plugA_Stop).state) {
        // plugA is OFF
        return false;
      } else {
        return {};
      }
    turn_on_action:
      - switch.turn_on: plugA_Start
    turn_off_action:
      - switch.turn_on: plugA_Stop

My question: does anyone know how to avoid that the switches, when coming back on available status, would be set to off in homeassistant?

Any help is really appreciated, as I spent already a long time searching for the answer in vain.
