LinKind Water Leak Detector

Devices & Integrations
1

Hi all,

Recently picked up a LinKind water leak detector, bargain at only £10ish.

Smartthings registers the device as “Thing” yet I can’t find a device handler that works.

Has anyone tried using these devices with any success?

Thanks

I have the same Linkind water sensors and have the same experience, they only connect as ‘thing’.

I would love to get these working with SmartThings as they are inexpensive water sensors at $10 each on Amazon, and have replaceable batteries, and seem well-built.

I finally found a DH for the sensor on the Hubitat forums which seems to work flawlessly:

Awesome thank you Matt!

Keep in mind that this is a Groovy DTH. The Groovy platform is set to be shut down on Sept. 30.

You need to find a compatible EDGE Driver.

Post the “Raw Description” from the IDE and many be someone like @Mariano_Colmenarejo can add it to their driver.

Would people use it if I converted the driver to Edge? I hadn’t yet mainly because I’m still in the “edge is not quite ready for primetime” camp.

I certainly would!

Unfortunately with the change to edge drivers getting closer and closer, alternative options aren’t really there!

Thankyou for your time and effort in developing the DH. I appreciate developing an edge driver for few people is more time and effort on your end however.

Just bought one of these. It seems to function just fine on the stock zigbee-water-leak-sensor driver once the fingerprint is added.

Cool, glad to know it at least works. Does the stock driver report both battery % and battery voltage? The device supports both natively and my driver supported both as I like to show battery voltage where its being reported from the device.

The stock driver does battery % but not voltage. Adding it doesn’t take much though - this will do both.

Excellent! Any idea what the stock driver sets the battery % and voltage reporting frequency to? I hard coded mine to 5 minute min, 60 minute max, .1V / 1% delta. I had wanted to make those adjustable parameters (at least max/delta) but never got around to it.

Thanks!

The stock for battery % is 30s min, 6 hour max, 1% delta. I used the same (but .1V delta) for voltage in the driver at that link.

Is this eventually going to be published to a channel or merged into an existing one?

Yes - @csstup is working on some refinements to help with battery life. I think he’s planning to publish once he’s finished testing.

@d3fung, It’s still being tested. So far it’s looking good.

For any ZigBee sensor (this is one) that provides both battery voltage AND battery percentage, I like to add voltage as it’s own tile, and store the percentage directly. The hope is the device has a “more accurate” percentage calculation than the translations in the framework. Who knows if that’s true but I like to see what the device reports native where possible.

For beta I’ll publish a channel. Long term I may try to fold it into one of the other “super” drivers (like @Mariano_Colmenarejo publishes) to help with the 50 driver limit.

Edge driver has been released. See more information here: [ST EDGE] Linkind Leak Sensor (model A001082)

Hi Corey,

Working great - many thanks for your work on this!

Glad to hear! Keep me apprised on battery life if you see any concerns. The radio usage is about on par with how the DTH was setup.

Just stumbled on this thread. This works perfectly for me! Thank you
