Hi all, I have a android built in wall display with led lights, gpo ports, 2relais and temperature and humidity sensor. I do have the API documents, but don’t know how to build an app for it. It’s also possible to connect via MQTT. Is there someone who could help me?

The model is rk3576_u also named as smt101

This is al the info i have, hopes that’s enough?

What’s the MQTT broker domain? Maybe it’s in the environment variables? You didn’t mention the domain/base URL of this MQTT broker.

And how do you authenticate? Is the MQTT username the email address of your account there? Also, what’s the name of the mobile/web app that you control it with?

Can we private message each other here? Maybe thats more easy
