Broadlink rm 3 mini works ok only once

I am unable to connect to my Broadlink RM Mini3 to hassio.
I get the following error when I call the broadlink.learn or send services.

2020-02-03 20:55:57 ERROR (SyncWorker_11) [homeassistant.components.broadlink.switch] Failed to connect to device
components/broadlink/ (ERROR)
2020-02-03 20:55:58 WARNING (MainThread) [homeassistant.components.switch] Setup of switch platform broadlink is taking over 10 seconds.

This is what i have in my config:

- platform: broadlink
    mac: 'C8:F7:xx:xx:xx:xx'
    type: 'rm2'
    retry: 10

The RM Mini 3 works fine with the IHC app and Broadlink Manager.

If I reset the power, it works OK but only once:
That is:
Power off
Power on
broadlink. service (learn or send) works but only one message

I am running ha 0.104.3 in a RPI3
Could someone help me??
