Water leak detector that will work with HA

Hardware
1

I have a water leak detector by Flo by Moen, but it’s only for leaks. I don’t have the water valve shut off. Looking for suggestions for leak detectors that will work with HA. Thanks

This video compares the most common ones that work best with HA:

I was holding out hope someone would put something together so I could use the Flo by Moen leak detector, but doesn’t sound like that is going to happen. thanks for the link.

There is this integration you can look into to try see if you are able to get your device(s) to work with your HA install.

I think I mentioned the leak sensor is not supported. I might be wrong here but I don’t wish to hack something together. From the video link you posted is there one or two you would recommend compared to the others?

Majority of folks get the Aqara one, which can also be used with a pressure mat to make a bed presence sensor as I found out recently from another vid.

I was kind of leaning in that direction with the one you recommended. I still need to get notifications setup so it’s going to be a while before I get email alerts and stuff

I use OpenVPN setup through my router to connect back home for both my HA instance via the companion app and my camera’s via the synology dsm app or to access files remote when I am out as long as I am on another wifi network I trust or have mobile data, I only have email alerts at the moment directly from my NAS for the scheduled health checks of the drives I have installed in it.

The other one I would suggest from that list is the Aeotec SmartThings Water Leak Sensor, its also zigbee based and it has a top and bottom sensor area so you can place it under pipes to detect droplets not just under flow so I would mix both based on where you need them.

For notifications I use this for my android phone when its for camera’s, the channel is auto created on the phone app then you just tell it in the phone app what mp3 file you want to use for the alert sound:

and for general notifications I use this:

To get the entities in the triggered by you need to put a name in for the entityID of the triggers. i.e in this case you would put in a name for each sensor so kitchen, bathroom, basement etc

i use the eve water guard. i have the bluetooth version (without thread), which is picked up by home assistants homekit device integration via bluetooth. while pairing it to home assistant is a bit complicated i really like how it works (with a sensor cable) and that it detects the slightest leak.

I recently heard Ubiquiti has a water leak sensor. I am a big Ubiquiti junkie and wondering if anyone heard of plans for this to work with HA? Many thanks

I got a Nous sensor which is working also with Zigbee ZHA integration. It took me a couple of times connecting it, but it worked.

Hi How you did this? I’m still not able to connect it.

13

i think after i found the manual it was just resetting it: nous E4 Water Leakage Sensor Instruction Manual
I’m using zigbee ZHA, not Zigbee2MQTT in this setup.

But i just noticed that the batty is already on 1%, not sure if that is true or if it really is sucking empty that fast.
I’ll get back, when i know more.

I have two types of waterleak detectors both are identified the same in Z2M. The round model tends to toggle when there is a bit water. This may drain your battery.

I use the other version (with a cable and contact with 2 small pins) to operate 2 pumps. Replaced the contact with an eurostekker to reduce the change water remains (capillary) between the contacts/plastic. Operation is frequently (87,000x) and the batteries (two AAA’s) are still on 100%.

You may want to monitor your battery operated zigbee devices. The option I use is a custom card “auto-entities”. This is still a manual action/look but gives a good overview. Below the yaml I use (you may want to exclude non zigbee devices).

type: custom:auto-entities
card:
  show_header_toggle: false
  type: entities
