Water leak sensors dropping offline

Aqara Products

I have an M2 hub centrally located in my home. I have multiple Aqara water leak sensors that randomly drop offline. They drop offline and then will reconnect at some point. Battery levels on all of them are fine and none are very far from the M2 hub.

Any recommendations to fix this?

Would an M3 hub work any better?

I could also opt to remove them from the Aqara hub and add them to Home Assistant via MQTT.

Thoughts or suggestions?

Thanks in advance.

Hello.
You can’t always trust the charge level in the app. If possible, check the batteries with testers, or better yet, replace them. This will be the first, main step in checking.
Another additional question, do you have any other Aqara devices that work on the network?

Have the same issue with one out of 4 installed water leak sensors. Check the signal level first and sources of interference near the sensors (metallic objects etc.). Try to put them in a different place for a few hours/days to see if it fixes the issue.

Hello @areine65 maybe the problem is in the repeater, bind the sensor directly to the hub by pressing the hub 3 times and the sensor should be switched to pairing mode. This may help you. After checking, please share the result.

All are bound directly to the hub. Unfortunately, they still take turns going on and offline. Seems to be a little less lately so living with it for now.

I have the same problem. Sometimes stable sometimes not.

Same here. Have 3 that go on and off line. They all have good signal. Must be a hardware or firmware defect.

I’d try adding a couple of Zigbee routers to strengthen the mesh before switching hubs or moving to MQTT, as that usually fixes Aqara sensor dropouts even when the hub is centrally located and battery levels are fine.

Seems like a common issue. I wonder if it’s a defect with the leak detectors

Hello, I think it’s most likely a problem with the Zigbee connections in the network. I will forward the problem to Aqara specialists @AqaraOfficial

The first thing you need to do is replace the battery and check it, because some sensors do not have indications of the battery status, so notifications about the discharge do not come and because of this, failures may occur if the battery is discharged.

Same issue, 6 devices, all will randomly drop offline, some come back, some take reinserting the battery.

Hello, check if the repeaters do not lose 220 volt power. There may be a voltage drop (for lamps) that work as repeaters. Also ensure continuous power supply to the gateways

Understand why we should check this, but all of my sensors are bound to my M3…

Thank you for sharing this topic. This was going to be my next Aqara purchase. From what I can tell Aqara still has the best water sensors. This is good info for when I put it in.

As I understand it, you don’t have any 220V devices?

18

Correct. I’m in the US and all my devices/wiring is 120V.

Are you having trouble taking sensors offline?

Problem is at it again in full force. At least 1-2 of the multiple water leak sensors go offline on a daily basis. Off then back then off again.

I’ve tried all recommendations listed above and from Aqara support. Nothing sticks. Problem returns.

Next step: replace with a water leak sensors from another manufacturer. I’m done with these Aqara water leak sensors. I am sick and tired of the daily multiple offline notifications.
