Just wondering if there is a way to do this using the Alexa smart home skill: https://www.home-assistant.io/integrations/alexa.smart_home/
As the Schlage Encode works with Alexa already, you could basically trigger the Alexa skill (lock/unlock) via home assistant: https://ledstripsandcode.blogspot.com/2019/01/how-to-trigger-alexa-routines-with-home.html
My understanding is you dont need to use voice, or even have an Alexa device?
I am unsure if this setup would provide HA the lock status back from Alexa though - is anyone aware if it would?
