I will try tomorrow in the near a relay.

You mean near a Gateway!

And given

could I build a development relay out of that?

Again if you mean a Gateway…..then NO!

Incorrect use of terms and implied lack of understanding of how LoRaWAN works suggests, as Nick says, you need to read more on the Forum and dive deeper into what LoRaWAN is and how it works and is implemented and what is supported on TTN. In recent times the concept of a LoRaWAN Relay has emerged from the development labs with a specific specification and set of criteria by which they, and any associated end devices, need to be configured and operated but its a bit specialist at this point and good knowledge of standard LoRaWAN (think Min 8 channel) and how that is different to the specific LW Relay (single channel - and definetly not a single channel packet forwarder) implementation should be thought of as key to success with the latter. Others may advise differently but suspect the EBYTE module isnt a good start point for such a project…..a bit like the tourist asking for directions to location XYZ being told by a local “you could but I really wouldnt start from here”!

update - I note Nick had also replied with same story by time I checked more on the module before I then hit send
