The new range of Google Cameras (still marketed as Nest) requires the
Google Home App. It now has integrated the Thermometer and Gas Central
Heating option. Just the Water Management and Boost facility is still
missing. They are getting there gradual...
As at January 2023, the Home App still cannot boost hot water, using
their Learning Thermostat. The Nest App seems ideal, but we are forced
towards the Home App if the newer cameras are required. The goal of a
single App seems a long way off still.
