Fan mode is not valid

[flybrys]

Recently updated the esphome code and now this error is showing in the HA logs:

Logger: homeassistant.components.websocket_api.http.connection
Source: components/websocket_api/commands.py:287
integration: Home Assistant WebSocket API (documentation, issues)

[140610517122016] Fan mode is not valid. Valid fan modes are: auto, low, medium, high, middle, quiet

Nothing specifically says its from this integration but its the only device I have that has those modes.

Functionally, I can't see anything wrong (yet)
