Mqtt ghost commands

I have a problem and I can’t figure it out.
I use a tostcorp controller for may somfy covers.
My somfy motors do not report the state, I’m just taking commands up, down,stop and pair.
For several months, every time I restart the host or my router the covers receive a series of commands and I don’t know from where.
Today I connected to the controller with Arduino Ide and I saw that when connecting to the network
they receive the following commands:

I tried with a new instance of home assistant but I did not manage to reproduce the problem.
