I have treated my protect detectors as a simple interconnected alarm system with zero smart or app function for years as the nest app has issues that i cannot rely on. If the Nest app did what it was capable of when i bought the detectors, it'd be fine to stay in the nest app alone. The urgency is that from Google's track record, "eventually" means never.
The product marketing shows cropped screenshots to show app functions without disclosing the app it uses. (A user would expect a google product to work in Google Home, but it seems convenient to not mention this doesnt work.)
My smart home app folder has multiple pages on it. Each manufacturer app, then a hub type app that supports MOST devices. I want one app that can control everything. Many manufacturers want the "as a service" model and dont want to allow outside control.
The nest app doesnt see any targeted development (does it get any dev?) it does not issue notifications to my device. It cant successfully silence alarms from the app, not being in Home is the reason i did not continue with plans to buy more nest products. It is easy for a company to announce progress in development without giving away secrets or setting firm deadlines. But with zero communication, and only getting a reply saying "its on the roadmap " after several years and pressure from users, doesn't give us any confidence it will happen. (Sounds like a partner saying theyll get around to that project someday.)
It was suggested i would be able to use the home/away sensors in Home integrations (doesnt work) and maybe if it was in home, i could program safety improving scenes, like a co alarm shutting down the furnace (nest used to advertise this function with its thermostat. Is that still a thing?) Or a fire alarm turning on all lights, opening blinds, shutting down fans, pausing music or movies, texting contacts, etc.
