Netatmo Smart Smoke Alarm Battery Life Experience

Hi everyone, I’ve been using the Netatmo Smart Smoke Alarm for a while now and I’m curious about others’ experiences with their battery life. I’ve noticed some inconsistency in my units—some last around two years while others go up to four years. Currently, two of my alarms are showing 25% battery life in HomeKit, which is a bit concerning.

I’d love to hear how long your Netatmo alarms have lasted and if anyone has tips for optimizing battery life. Have you noticed any patterns or environmental factors that might affect this? Any advice would be greatly appreciated! :blush:
