A: Hi there, thank you for your inquiry. The new Google Nest Learning Thermostat (4th Gen) does not require a sensor to function properly. However, for optimal temperature control and comfort, we strongly recommend using a sensor. You may also place the Google Nest Temperature Sensor in a different room to monitor and control the temperature in that specific area.
A: Hi Sparkz. Thanks for your inquiry. The Nest Learning Thermostat 4th Gen requires a specific mounting bracket and wire harness that's different from previous models. Please use the ones included with your new thermostat.
A: Hey there. The Nest Learning Thermostat 4th generation typically activates the AC or heat when the ambient temperature deviates from the set point by a small margin. This margin is often around 0.5 degrees Fahrenheit. It's important to note that this can vary slightly depending on factors like the specific settings on your thermostat, the efficiency of your HVAC system, and environmental conditions.
Q: Is it compatible with apple homekit ?
A: Yes, it is finally compatible with Apple HomeKit using Matter.
Q: If the WiFi goes out can I still control the temperature manually?
A: Great question, Kat. The Nest Thermostat Gen 4 will continue to follow its set schedule even without Wi-Fi. While you won't be able to control it via the app when it's offline, you can still adjust the temperature directly on the thermostat itself.

Q: Does the Nest work with base board electric heaters

I’ve owned every Nest thermostat since the first generation, and this is by far the biggest improvement yet. The bright display is highly customizable and keeps all the familiar Nest features, but in a sleeker, more modern design. Setup and control now run through the Google Home app rather than the legacy Nest app, so that is important to know before you upgrade. Google is phasing out older Nest models, and this unit is an excellent replacement if you are still using one of those. The included remote sensor is especially helpful in multi-level homes, allowing the system to detect cooler areas, such as a basement, and adjust heating to keep the whole house more comfortable.

This is an easy to install and easy to use thermostat. It is actually smart and adjusts to your needs. While you need Google Home to set it up and dive deep into some features it also works with Apple Home. You can have Siri adjust the temperature just by asking. Also the look is amazing
