Deploying new functionality to running actor system

My boss has had a look into Akka. He said that “after all my testing and looking into my requirements for the past 2 years, Scala with its functional and object oriented aspects combined with Akka is an unbeatable environment to work in.” I thought it would be nice to start off with that ;)

He is hoping to use Akka in an IoT project with lots of devices, where he wants the devices to communicate over the network using Akka Actors. He asked me if it’s possible to deploy new “rules/functions/code” on his devices using Akka. As I understand it, he doesn’t want to manually ssh into every device and update the jar, but there should be an automatic mechanism to update many devices at once.

I’m not sure what the options are for this, so I’m asking here (and letting him know). If there is a solution above the scope of Akka, of course that would be helpful too.
