I am a beginner, I do not have any equipment yet.
In my environment, unfortunately, no gateway is available.
Of course, before I invest a lot of money I would like to test if I could integrate mqtt data into my home automation system.
Is it possible to subscribe to a test topic via mqtt mosquitto (subscribe) on a trial basis.
as far as I know there’s no test MQTT channel
create an application in the TTN console, add a (virtual) device to that application, and simulate uplink.
In my opinion, is it useful to make some devices and applications for testing publicly available?
Setting up a dummy application and device and then simulating uplinks works well for testing MQTT.
That would be the way to do it
Remember the username is your AppID and the password is the App Key.
Thanks a lot, I will try it.
