I have about 15 water leak sensors and a few just randomly drop offline even though the Zigbee signal says “good”. Any thoughts? A reboot of the M3 hub will fix this but then it will happen again, just for note, both that seem to give me issues are sitting on tile floors behind a toilet.
I have the same issue with one old water leak sensor (not T1 model). I suspect the issue is interference in the ZigBee signal (although it may not show in the signal status). Try moving it closer to the hub or to entirely different place / room for a while to see how it behaves.
This is the newer version of the sensor, and the controller is in close proximity to to this sensor but I will move it closer…it did just pop back online so it seems intermittent now.
Hello @pchiccino_aqara
Connect the sensor directly to the m3 hub, you need to switch the sensor from the pairing mode and press the button on the hub 3 times and the sensor will connect. Test its operation after these manipulations.
@raman.v Are you saying after it is connected and showing in the hub i need to press the device 3 times to take it out of pairing mode?
Same here. it happens to me a couple of times a month as well.
I have solid Zigbee coverage in the house (around 110 devices on this network), but still, 1 or 2 water leak sensors occasionally go offline.
They usually reconnect on their own a few hours later without intervention.
The last time I noticed a small wave of disconnects was just this past weekend.
So you’re definitely not alone; seems like a minor stability issue that comes and goes.
Exactly what is happening here, seems to be the same two devices, both show either good or acceptable Zigbee strength but will drop on occasion, they do reconnect as well. Interesting thing is that apple home still shows them online and if I trigger them with moisture they still fire the water value.
Make sure they have the latest firmware and then I would suggest to contact aqara support
Currently up to date on all firmware if it continues to be an issue I will reach out to support.
I have two houses linked to my account. When it happens, it affects both houses; always water leak sensors, smoke detectors, and occasionally motion detectors.
Hello @pchiccino_aqara . Considering that the leak sensor has its own pstrong texteculiarity, it is almost always “lazy”, works as intended very rarely (water leaks). All the time it only sends a communication signal “I am here, I am dry”, I wanted to check the period of sending the polling signal.
I will analyze three leak sensors.
- Sensor 1, works in the automation of controlling the lower water level in the water tank. Connected to the M2 gateway directly (I made this sensor critical, direct binding to the gateway).
- Sensor 2, works as intended, monitors the disappearance of the industrial network (using dry contacts of the relay connected to 220 volts). Connected to the M2 gateway directly (I made this sensor critical, direct binding to the gateway).
- Sensor 3, located in the bathroom under the sink, works as intended (water leakage under the sink). Attention, binding to the M2 gateway through some kind of repeater (some Aqara device in the room). I know this because when the industrial network disappears, it is not on the gateway (disconnected).
I compared the level of Zigbee signals of each sensor and was surprised.
1 sensor is involved in active automation when pumping water into the tank at the moment the automation is triggered (the condition is that the water level has decreased to turn on pumping) sends a signal and the Zigbee communication level is measured, which is displayed on the graph.
2 sensor constantly waits and sends a Zigbee polling signal twice a day, again, twice a day, this is a very long period. The sensor is connected directly to the M2.
3 sensor through a repeater, the signal level graph jumps throughout the day as it wants. Although it is constantly dry.
Based on the above, some sensors have an incomprehensible algorithm for sending polling signals to the gateway when they are operating in standby mode.
This problem would be easily solved if Aqara specialists gave the user a map of Zigbee connections. There was talk about this once, but it’s still silent.
@AqaraOfficial , are there any developments in providing a map of Zigbee connections for a smart home?
Thanks for the answer.

Α map of ZigBee connections is a good idea as it would allow us to do better troubleshooting
I appreciate the detailed information. Very helpful.
