Hi,
just wanted to share a cool IOT plattform (flespi.com or flespi.io)…i got my data from the TTN via mqtt into Flespi.com. From there i can forward it to wherever i want (in my case to thethingsboard via mqtt… so flespi works as a mqtt-client into the TTN direction and as a mqtt-client (sender) into the thingsboard appliction… works great and costs nothing (developer version)…
Enjoy
Wolf.
