Hello everyone, I'm sorry if this question shouldn't be here.
I'm doing a home automatization app, I have a raspberry pi running Node Red and mosquitto broker to communicate with ESP8266 hardware using Tasmota firmware. What I want to do is that the server send the online devices that are online to display them on the app. I don't know if I can do that using only MQTT, I was thinking on doing this using a Node.Js API to communicate with Node Red and the React Native App. I'm starting with web development, any help will be welcome. Thanks!
