To the product owner of the dev team:
I would highly recommend you prioritize writing some docs or an extra set of APIs to expose some of the basics (All I would require is the ability to triggering a zone for x minutes.)
Currently there arent many turn key solutions in the market and enabling the home automation crowd would do product sales wonders I can assure you!
Here is a view of whats available for home assistant, as you can see its slim pickings and rachio is the only other turnkey product that was as easy, accessible and priced as b-hyve.
You dont even need to write the integration yourself, If you show us how we will do it for you 🙂

PS. Is it possible to trigger a zone for x minutes from this interface?
