has way too many things

In short: added the ability to detect when a device has disconnected.
From this we have to achieve a way of:
- reconnecting the device
- re-subscribing to the fields it needs (it should already be subscribed
since the ESDI didn't stop tho - but for the sake of it, or in case a
device joins later)
- start sending data to it (which should be automatic given how we are
handling the devices)
