Linkind water leak detector $15

Zigbee water leak sensor. Regularly $20, now has a &5 coupon.


From the screenshots, it appears as a generic sensor. Have you tested how Hubitat reports a leak alarm from the sensor?

I changed the type to above and it works fine. If I dip it in water it sends an alert its wet. I take it out and it states it’s dry.


Maybe @mike.maxwell can add the fingerprint in one of the 2.2.9 revisions...


Thank you for posting the Amazon link, and the required device type change info.

Great price, paired easily, and works well with HSM. Had to read the tiny micro print instructions to figure out I needed to press hold the black factory reset button on the bottom to get it into pairing mode.

I had the same experience with HE. It paired as a Zigbee Contact Sensor, I changed to the Zigbee Generic Moisture Sensor and its working fine. Added to HSM clean.

Note that I wasn't able to get it to work under ST. Detected as a Thing, changed to SmartSense Moisture Sensor but still wasn't able to read any data.

Thanks for the alert!

Looks like the coupon is gone but it seems like a good deal even at $20.

While I was looking at related items I saw quite a few new names for inexpensive devices.

Also, Aeotec brought back the "Samsung" water detectors we know and love. They do cost twice as much.

Is it worth the extra money for mission critical leak detection? If a motion detector fails to trigger a light it's no big deal.

Besides the cost difference, my comparison to the (Zigbee) Smartthings vs Linkind leak sensors:

Smartthings Leak Sensor SmartThings water leak sensor β€” Aeotec Zigbee sensor

  • CR-2 battery
  • Internal temperature sensor
  • Contact probes on bottom and top (for gen2 model, the latest)
  • Had been out of stock since the hardware cutoff of Dec 2020. Aeotec has started shipping new ones recently but availability isn't 100% yet.

Linkind Leak Sensor

  • Uses 2 AAA batteries
  • Built in siren. Says 85db or 90db, but my experience is that if its inside a cabinet or in a closet you're not likely to hear it unless you're nearby anyway.
  • No temperature sensor
  • Probes on bottom only
  • Documented as Zigbee 3.0
  • Paired, but wasn't able to get data into ST. Worked fine for HE.

I've had the Smartthings leak sensors running for over a year, and they've worked great, down to about 70% battery reading with an ambient temp of 60-75deg F.
The Linkind I just added last week to HE and its polling normally. I ordered 4 more to continue to test.


Thanks for the comparison. AEOTEC has it all going on over the Linkind, BUT Linkind's AAA batts trump Aeotec's advantages for me, because I have had great success hardwiring devices with the following battery replacements and a USB brick so I can "set it and forget it."
