Some zigbee devices not discovered after upgrading to 2MQTT 2.0

I´ve upgraded to 2MQTT 2.0.0 with the suggestions I have read. I´ve also upgraded the dongle (Z2M) to “ember”, and wrote this interface on config.yaml file. Everything works OK, except that I have lost my Sonoff ZB Mini L2 switches (without neutral). I can’t find a solution since then. Can´t get any discover of these devices in the Z2M net.
I am working with Raspberry Pi 4 with OS HA 14.2 . I´ ve just upgraded to 2MQTT 2.1.1-1 and HA Core 2025.2.2 and the problem continues.
Thank you very much in advance for any suggestions you can provide me.
