Hello,
As many people seem affected by this delay, I finished developing the z2m ember driver and the Docker image is available for testing here: docker pull cicoub13/gladys:z2m-ember
Details:
- to allow people who haven’t updated, I kept the (legacy) driver
ezsp 
Migration is automatic for people who have a dongle from the list (without firmware verification). I think the majority of people won’t have any issues, but this may break setups of people who do not have firmware > 7.4.x
@pierre-gilles we can revisit this choice- new installations choose their dongle from the list and have the
emberdriver
I’ll test all scenarios today or tomorrow on my RPI4 
To update the firmware => Sonoff Dongle Flasher - SONOFF Dongle
