Wyze Band with Alexa: what can it do?

I want to write Alexa skill. Anything I can read up?

Specifically I want to achieve Remote pulling info from Wyze band:

  • Alexa, Take my heart rate
  • How many steps today
  • How’s my sleep

Alexa doesn’t seem to interact with the watch (not built into the Alexa Skill). The watch interacts with Alexa (it serves as a mic for Alexa, allow you to give it voice commands).
