There were a couple of users that were discussing using Pi's as middle men - not sure the status of this.

Anyone out there that has done this that can help Bernstein?

As mcJohn mentioned, you can also forward the information to a service like CloudMQTT as an option. They do have a free tier and there are other ones out there as well. To help, you can check out this video that walks-through setting up CloudMQTT as a service. On this video we subscribe to the topic on an Android phone to view the data so not quite what you are looking to do but hopefully it helps a bit (CloudMQTT stuff starts around the 0:50 mark)
