Nest API shutting down

They’ve just announced that the Nest API will be shutdown in August.

I’m really bummed because I’ve just bought 7 Nest Protect smoke alarms, 4 boxes were opened, and the other 3 haven’t even been unwrapped.

I guess this means they can no longer be controlled / interfaced directly with openhab.

Does anyone know whether it can be used in openhab via the “Works with Google Assistant” ecosystem? I’m not familiar with it at all.

oops, sorry there’s already another discussion about it here
