But, from my MQTT client (MQTT Explorer), I don’t manage to have the bell triggered even if I sent the same paylaod to the same topic, which I can verify was correcly sent. Any idea what I’m missing ? Does HA take into account messages sent by external script on the a device’s topic ?

my bad, I sent the payload to the topic zigbee2mqtt/mydevice instead of zigbee2mqtt/mydevice/set
All good now :+1:
