We are happy to announce that lock control and query capabilities are now also available to developers building skills for the UK.
Developers targeting devices with locking behavior can now enable customers to issue a voice command such as "Alexa, lock the front door," or "Alexa, is the front door locked?"
The feature, previously announced in the US, is currently supported with a SmartThings hub in the UK. The Smart Home Skill API simplifies development efforts as everything is managed through the Alexa.ConnectedHome.Query namespace.
To get started, see the documentation on lock control and query. To learn more about developing a smart home skill check out these resources:
