my english is not verry good but i try to explane it.
I already use Node Red on a rasberry for my dashboard. I have installed this on node red node-red-contrib-miio-roborock (node) - Node-RED
There u can controle the roborock with the IP adres and the token. U get 2 node’s, one for control and one to read the status of de roborock.
It’s verry easy to set it up (if u already have a raspberry and node red installed on it…
If u wanna no how to instal node red and mqtt u can look at this topic
I hope u understand my bad english
