Add control to a Z-Wave device via MQTT

quick Introduction: I have been a Jeedom user for 3 years and recently started exploring Home Assistant (HAS) with various devices, including Z-Wave and Zigbee, using MQTT. For a smooth migration, I have kept the MQTT broker and dongles on my Jeedom server. My Home Assistant setup is on Synology (container) under DSM 7.2.1. I successfully connected MQTT to my broker and published my Z-Wave and Zigbee devices without any issues using the Web UI of Z-Wave JS and Zigbee2MQTT.

Description of the problem: I use Eurotronic Thermostatic Valves for my radiators. Since switching to Z-Wave2MQTT (even on Jeedom), a command has disappeared: the manual mode (zwave/41/64/0/mode/set with value=31), where the valve position can be manually controlled. In Jeedom, adding this command is straightforward in the list of commands, and I can control my valves.

The question is how to do it with HAS ?! :slight_smile:
