@margusl Lookos good, but it is only for Ambit 1 and 2 watches and I have Ambit 3.
Are you referring to project desription or Moveslink2 actually failed when syncing Ambit3 with mock server?
As you asked if you could write a local service, adjusting existing mock should be quite trivial compared to writing one from scratch.
Anyway, what problem are you trying to solve by service mocking? If you just want your activities as GPX, it’s way more convenient converting Suntolink2 SML files or using Openambit instead.
