Moisture Sensor Problems

Hey all, I have three Smartthings water sensors placed throughout my home, however 99% of the time they are in an Offline mode. The type I have purchased is below.

Has anyone had similar experiences with this model? If so, is there a fix?

Is there a model that you would recommend for moisture?

Samsung GP-U999SJVLCAA Smart Things Water Leak Sensor - Automate Lights & Siren For Alert - ZigBee | Accessory to Smart Things Hub White https://www.amazon.com/dp/B07F951JDP/ref=cm_sw_r_cp_api_i_UGQ9DbB96DW9C

Hi,

I have also 3 SmartThings Water Leak Sensors model GP-U999SJVLCEA, but until now without issues.

I also have 1 Xiaomi Leak Sensor. I had to reconnect this Xiaomi sensor 1 time after it went offline.

The Fibaro or the Aeotec Water Leak sensor could be an alternative.

I have several of varying versions, including ones like yours. All work great. Your offline issues could be related to distance from the hub or a zigbee repeater, interference, or battery issues.

Besides your ST hub, what other zigbee devices do you have that are repeaters, like switches or wall plugs? How far away are the sensors from the hub or repeater device?

The devices are quite far from the hub without any repeaters, so that very well could be the issue. Would you know or recommend of any repeaters to enhance my coverage?

Specifically ones that work with the new App. I have seen online where some only work with classic.

I’ve not seen any yet that won’t work in both, especially since the device handlers (stock ones) work with both apps, heck even custom ones work if done right.

Anyway, I have over 100 devices that are repeaters. I use primarily GE devices (in wall switches and wall plugs), but they can be pricey. I have several of the ST branded outlets that work great, Centralite/Iris/Older ST outlets, and several Innr outlets.

Here’s what I have:

If you are able to find a centralite 3210, you can get both zwave and signed repeaters in one device. I believe you can find a few on eBay, used…

You all have been a ton of help, thank you! I ordered a centralite to try! Hopefully that will help my moisture sensors, thank you!!

Anytime! The way you’ll know is to check in the IDE, and look at the sensor to see where it’s next hop is going to be. Here’a an example of one of mine:

Check what it is now, and then again after you add the Centralite and rejoin the sensor close to the outlet. You should see the Next Hop be your new outlet.

In addition to John’s excellent advice, I would add to consider drawing a layout of your residence and devices and strategically place the new repeaters to maximize coverage. After everything is included and placed in their final position, I would turn off your hub for at least 30 minutes, and then turn it on which will initiate the zigbee network remapping. There are many helpful threads that discuss this process.

BTW, if you were able to find the 3210 plug, you will need to read the threads regarding implementation of the zwave portion of the plug.
