Run ESPHome dashboard with systemd when installed in a venv

Hi everyone,
I would like to run ESPHome dashboard as a service, it is installed using a venv on debian 11.

I have tried to create a new service unit file called esphome.service in /etc/systemd/system/

Description=ESPHome Dashboard

ExecStart=/root/esphome/bin/esphome config/ dashboard


It starts ESPHome dashboard as a service, but it does not absolutely works as (I think) it cannot find the config folder correctly.
Anybody had this issue or can figure it out?

Many thanks!
