Domo has a data framework reliant on data types.
These define what kind of data the property holds.

| `0x00` | `None` | 0 bytes | Nothing | Nothing, mostly used internally or as example. |
| `0x01` | `bool` | 1 byte | Switch | A simple switch with two states. `0x00` = off, `0x01` = on, `0x02` = toggle |

## Dynamic data (`dynamic_data`)
Dynamic data is a data snippet with a `prop_data_type` byte and the data next to it.

| offset | size | name | description | example |

| `0x00` | 1 byte | `prop_data_type` | Describes the data type | `0x00` |
| `0x01` | depending on `prop_data_type` | `data` | The data | |
# Commands
These are the default commands. All Domo nodes should support these.
