Hello,
I´m running a Node-RED-Server which normally is controlled with the help of the dashboard. In the office, there is an other dashboard (based on Excel with VBA) running already and will not be changed.
Is there a comfortable and secure way to control 10 devices (relays, servos, motors) or should I use http-requests? At the moment I use http-requests to show the state of the relays. If the relay is on, the http-response is "true" and so on.
Thank you
Michael
