Whats the easiest way to get the key? Decoding the token? Maybe it would be a good idea to provide it with the token when you create a new access key? And/or rename the button to "Add new (Access)Token" it's a bit confusing if you are looking for a key (-k) Adding the openWRT as node was not that difficult when you have everything 🙃

./netclient-armv7 join -k (Decoded Token:"key":"SuperDuperSecret"--grpcserver grpc.Server.tld:50051 --network test --daemon=off

And via the Webinterface you can add a cron (System->Scheduled Tasks): */10 * * * * /etc/netclient/netclient checkin -n all
