All commands must be written as `{"cmd":<cmd> ,"data":<data>, "id":<n>}`.
The `id` can be replaced with `hc` for some devices. `cmd` and `data` must be enclose in quotes as a string.
The `id` can be replaced with `hc` for some devices and represented as a string or a number. `cmd` is a string, `data` can be a string or number.
