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)
