+The `metoffice` weather platform uses the Met Office's [DataHub API](https://www.metoffice.gov.uk/services/data/met-office-weather-datahub) for weather data. 
 ## Getting started
-Their website is not as straightforward so check the [getting started](https://www.metoffice.gov.uk/services/data/datapoint/getting-started).
-1. Register for a [Met Office account](https://register.metoffice.gov.uk/WaveRegistrationClient/public/register.do?service=datapoint). 
-2. After registration and verification of your account, [login](https://register.metoffice.gov.uk/MyAccountClient/account/view) to retrieve your API key.
+1. Register for a [Met Office DataHub](https://datahub.metoffice.gov.uk/) account. 
+2. After registration, [subscribe](https://datahub.metoffice.gov.uk/profile/subscriptions) to [Site Specific Global Spot](https://datahub.metoffice.gov.uk/pricing/site-specific) dataset to obtain your API key. Free tier subscription gives 360 calls per day which is enough for using this integration

 ## Entities
 
-This integration creates a number of weather entities for each entry created in the configuration by location: one weather entity with a summary and a forecast, and twelve sensor entities for individual reporting on each of the individual measurements, for both 3-hourly and daily updates (to a grand total of 26 entities available). Note that only one of the two summary entities and the 3-hourly sensor entities flagged below are enabled by default, so your system isn't overrun on initial configuration. The time supplied for each forecast is the start time for the forecast.

 The available sensor entities:
 
 - "feels like" temperature
 - humidity
+- pressure
 - probability of precipitation
 - station name
 - temperature
 - UV index
 - visibility
-- visibility distance
 - weather
 - wind direction
 - wind gust
 - wind speed
 
-Only probability of precipitation, temperature, weather and wind speed are enabled by default.
