Dear all,
As we know, the default airnode for one zone is one airnode. But I
want to set 2 or more than 2 airnodes in one zone. Please tell me the
detailed steps how to set 2 or more than 2 airnodes in one zone?
Furthermore, if I set more than 2 nodes, which advantages has
it better than only one node in one zone?
Many thanks in advance!
Br.
