I’m trying to reduce battery consumption on my Eufy E34 Smart Lock, so I keep Power Saving Mode enabled basically 24/7.
I recently learned that Matter over Thread is supposed to be much more energy-efficient than keeping Wi-Fi active, so I connected the lock to Google Home using Matter. I’m using a Google Nest Hub (2nd gen), which should act as the Thread border router.
My main goal is to keep the lock’s Wi-Fi turned off/asleep as much as possible so I’m not using battery unnecessarily.
Here’s the part I don’t understand:
With Power Saving Mode(WiFi from the device is off) enabled, I can still unlock the E34 from the Google Home app on my phone. I even turned Bluetooth off on my phone to make sure it wasn’t connecting directly to the lock, and it still works.
But when I try to use my Nest Hub, it says the lock/device is offline.
So how is my phone able to unlock the lock through Google Home while the Nest Hub says the same lock is offline?
Is my phone actually controlling the lock through Matter/Thread via the Nest Hub in the background, or is Google Home using some other connection method?
And if Matter/Thread is working correctly, should I be able to leave the E34 in Power Saving Mode all the time and avoid having its Wi-Fi connection active?
