Nest and Google are both owned by Alphabet and it would seem like there should be a lot of tight integration between Nest products and Google services. After pairing the Philips Hue to Google Assistant in this review, we next wanted to set up our Nest Protect and Dropcam (now part of Nest) with Google Assistant.
Unfortunately, we found that Google Assistant only seemed to support the Nest Thermostat.
After connecting Nest with Google Assistant, we weren't able to find the Nest Protect and Dropcam in the list of Home control devices. Even after we went back to the Add devices screen, there were no Nest devices linked.
We also linked Nest to our Alexa account in the Alexa Smart Home screen.
All the Nest related documentation from Google Assistant and Alexa App seemed to focus on the Nest Thermostat so we assume at least this device is supported. However, it's surprising that premium Nest smart home devices like the Nest Protect and Dropcam don't seem to be supported even by Google's own Assistant App.
