Hi Caffy, thanks for sharing the details of your feedback about the Nest Protect. We’re sorry to hear that you came across this Pathlight feature issue. We have tested Nest Protect's light brightness range to ensure the best performance while preserving battery life. The default setting is bright enough to light your way in the dark without draining the batteries quickly. Changing the brightness will affect its battery life. Nest Protect’s long-life LEDs have been rated to exceed the product lifetime (7 years for 1st gen Nest Protect, 10 years for 2nd gen), so Pathlight should work for as long as your Nest Protect does. To change settings: - Tap the Settings Nest settings icon on the Nest app home screen. - Scroll down and select the Nest Protect that you want to change settings for. - If you want to change Pathlight brightness, select Brightness. Then choose Low, Medium, or High. If you want to switch Pathlight on or off, Select Nest Sense, then select Pathlight. You can then set Pathlight to On or Off. If you have a wired Nest Protect, you can also choose Always On. Important: The brightness and on/off settings you choose will also affect the Nightly Promise light. However, even if the light is set to off, your Nest Protect will continue to test itself and the Nest app will let you know if everything is OK or if there's a problem. - Changes to Nest Protect’s Pathlight settings will take effect within a day for a battery-powered Nest Protect and within an hour for a wired Nest Protect. A clock icon in the app indicates the pending change. - To update Pathlight settings immediately, press the button on your Nest Protect once.
