Looks like the easiest out-of-the-box integration would be to set up your Bond bridge to talk to a custom MQTT broker, and then use the pre-existing MQTT Binding.
I’m in the process of trying this myself and will report back here if/when I get it working.
UPDATE: I asked on the BondHome forums about the MQTT binding and unfortunately it is very poorly documented at the moment, so it looks like this is not an easy path to integration
