Add Missing Model and Serial Number Fields

[jim0020]

If one were to add the model and serial number of the WaterFurnace heat pump unit, where is the best place which conforms to the homie way of doing things? Would it be under the topic /homie/aurora-xxxxxxx, or /homie-aurora-xxxxxxx/abc, or under a new node?

As new properties under abc.
