Hi all,
I successfully set up a gateway with a raspi3 and an ic880a. I successfully programmed a T-beam as a node. I successfully registered the gateway and the node at ttn. I see the gateway and the node payload on my console.
I want to access the data with an application ( an .exe 
) from my desktop computer, preferably in Python. Somebody has a pointer to some example?
I’m a bit overwhelmed and confused by the wording: device, node, application …
Thank you
Detlef
Here’s more words:
MQTT and Data Integration
Look at the pages on https://www.thethingsnetwork.org/docs/applications/mqtt/
There are Python libraries that will provide MQTT that you can use to receive data as it arrives at TTN and process it as you want. Be warned, this only works if your program is running all the time - so don’t run it on your desktop machine if you turn it off at night!
There are other mechanisms as well - in the Application page of the web console you can add integrations that will either store the data for up to 7 days on TTN servers, or pass it on to one of your own servers or allow other services to receive or access the data - there are many choices.
