Hi - I am afraid not, the plugin only supports the specific wifi controllers (and some associated models) and uses a reverse engineered set of API calls.
The good news is they do have a supported and documented API
https://daikinone.com/openapi/documentation/ but unfortunately it is a completely new structure so adding support would be essentially a new different plugin. It looks pretty straightforward but without a device to build/test against it wouldn't be something I could do.
I will update the documentation to make it clear it does not support the One+
