Have just installed my Ecodim .07 ZigBee and integrated via ZHA. Works like a charm, no problems at all.
EDIT: Unfortunately I found an issue with the dimmer when being controller from within home assistant, see this post Ecodim .07 ZigBee Dimmer Issue: Incorrect State Updates for On/Off Actions
EDIT 2: I have found a workaround for my problem (see link) and am now happy with the dimmer.
