Yes, but when you do this, you are NOT using Zeus's self-custody node - on - the - phone. You are essentially just using Zeus as a mobile interface for your Umbrel or Start9 node.

We have been talking about trying to use the node-on-a-phone option from Zeus with Alby Hub. To my knowledge, there is no way to do this. 

 Or rather, as an interface for a particular wallet hosted on your Start9 or Umbrel node. 

 You can use an LND node as a funding source for Alby Hub. I don't know if Zeus allows allows such connections.
