Excited about Aqara. Does anyone use water sensors and how is battery life?

Hey everyone :wave:

I’m starting to go further down the Aqara + HomeKit rabbit hole and I’m honestly pretty excited about how much value they seem to pack in for the price. Before I go all-in, I’d love to hear some real-world experiences from folks who’ve been living with Aqara gear for a while.

A few things I’m especially curious about:

Water leak sensors

  • Does anyone rely on Aqara water sensors for things like basements, water heaters, or under sinks?
  • How’s the battery life in practice? Are people actually seeing the multi-year life Aqara claims?
  • Any false positives or missed leaks?

HomeKit integration

  • Where exactly do the Aqara sensors show up in HomeKit (room placement, categories, etc.)?
  • Do they behave reliably in automations and notifications?
  • Any quirks with delays or “no response” issues?

Hubs & ecosystem

  • Which hub are you using (M2, M3, G-series camera hubs, etc.) and how stable has it been?
  • Are you running Aqara mostly standalone, or mixing them with other HomeKit devices?
  • Any strong opinions on Zigbee vs Matter with Aqara so far?

General reliability

  • How long have you been running Aqara devices?
  • Anything that failed unexpectedly or needed frequent re-pairing?
  • If you had to start over, would you still choose Aqara?

I’m especially interested in long-term experiences — the kind you only get after living with sensors quietly doing their thing for months or years. Wins, regrets, weird edge cases… all of it is welcome.

Looking forward to learning from the hive mind :smile:

I’ve been using their water/leak sensor for just over 5 years.

Have had several leaks in my garage and kitchen because of the bad plumbing, and it has been perfect.

Super rock solid, long battery life. I have no idea how long it lasts, but it’s not even on my radar because it’s just not an issue.

Edit: never had to re-pair. Have one under every sink and behind every toilet, one under a drip loop by my water heater. I probably should add another in the water heater pan, too.

Using an M2 hub and it has given true and occasionally false positives when there’s been a leak under a toilet. But so far I’m ok with the rare false positive, prefer it over it not notifying me when there is a leak. I wish it was more apparent if the signal is too weak when I set the puck up further away.
