then you should do just fine without this extra separate flow.
In my case, I run my nodered dashboard on a Synology NAS on the local network.
For more information on how to create dashboards, many examples and guides exist. In this community I learned a lot from Node Red: A widget based dashboard working with Homey trough MQTT - there you can also see my own dashboard pages (I have 5 by now) but here’s inspiration: Node Red: A widget based dashboard working with Homey trough MQTT - #621 by RogerSt
Other dashboards are for example the HomeyDash: Homeydash.com , een Homey dashboard
Have fun reading - there’s tons of inspiration, examples and explanations in these community topics.
