@gafich10 and you were right because I wrote that in the first place as a second bullet point. The screen I attached correspond to option mentioned by you @Raman.V
On Samsung One UI you can reach it from different places but it is same - allowing Android to put app into sleep causing sometimes notifications not being able to show up. So it means that unfortunately problem is somewhere else because this option is from the beginning set to exclude Aqara Home from this (on both Android phones).
Sure! Here’s the same answer in English, tailored for Samsung devices (One UI) to ensure Aqara Home push notifications work reliably:
1. Allow background activity for Aqara Home
Settings → Apps → Aqara Home → Battery
Select: “Unrestricted” or “Allow background activity”
This is critical — otherwise Android may “sleep” the app, blocking notifications.
2. Enable auto-start and background data
Settings → Apps → Aqara Home → Mobile data
Make sure these are enabled:
Allow background data usage
Allow data usage while Data saver is on
3. Disable battery optimization for Aqara Home
Settings → Device care → Battery → Background usage limits
Find Aqara Home and make sure it’s not restricted
Alternative path:
Settings → Apps → ⋮ menu (top-right) → Special access → Optimize battery usage
Search for Aqara Home
Set to “Not optimized”
4. Enable all notification permissions
Settings → Notifications → Aqara Home
Enable:
“Allow notifications”
“Show on lock screen”
“Pop-up notifications”
“Sound / Vibration”
Also check inside the Aqara Home app:
Profile → Settings → Notifications → Enable all toggles
5. Exclude Aqara Home from power saving
Settings → Battery → Power saving mode
Either turn it off or add Aqara Home to exceptions
Extra Tip
Ensure Wi-Fi stays active while the phone sleeps:
Settings → Connections → Wi-Fi → Advanced → Keep Wi-Fi on during sleep → Always
Want to test it?
Create a temporary automation in the Aqara Home app:
“If door opens → send push notification”
→ Then trigger it and check if the push arrives.
If you share your exact model (e.g., Galaxy A52, S21, etc.), I can provide even more precise steps — some Samsung phones also have Adaptive Battery or Deep Sleep app lists that need adjusting.
Let me know if you’d like that!
Look at the artificial intelligence’s answer, maybe there will be a clue for you.
As the developers say, in most cases he comes up with something he doesn’t know the answer to, and this happens extremely often.
So today I changed location of one of my FP2 sensor and I added it again on my Android phone (Sensor options ⋮ menu (top-right)> Device Setting > Detection Mode > Install Now button…). Previously whole system was configured on iPhone. But once I added it again on Android notifications from Aqara Home started to show up. So if anyone will have similar case try to remove one of the device and add it again. Looks like it triggers something? I don’t get it but for me it worked
