Any suggestions for what to check on this? I have like 5 of these and only 2 are doing this. I have done changed any configurations specifically on different devices (knowingly anyway haha)
What kind of batteries are you using in them? Some batteries don't report correctly. About the only one I would worry about though is that first one. It's likely going to need replaced
How long have the batteries been in the device. Normally batteries last a very long time in leak sensors.
Standard alkaline batteries have a smooth decrease in voltage over the life of the battery, so battery life is easy to predict. In contrast, the lithium batteries used in many devices hold their voltage until they near the end of their useful life. Then the voltage plummets. Since your battery life indicator plummeted over a few days, I suspect you are using a lithium battery in the device and it is now time to replace it.
I always keep a stash of various lithium batteries on hand since the devices do not give you more than a few days warning that the batteries are failing. Once the voltage starts to drop, it is time to replace the battery.
The one exception to this rule is if the device is kept in cold temperatures such as a freezer or outdoors in freezing temperatures. I use a Smartthings multisensor to measure the temperature in my garage freezer. I put a new battery in the sensor. Within a few hours, the battery life indicator showed only 1% life remaining, but the sensor keeps sending data to the hub. The only way I will know when it is time to replace the battery is when it stops checking in with the hub. I suspect I will have a similar issue with my outdoor motion sensors this winter when temperatures drop below the temperature in my freezer.
Thanks to both of you for weighing in -
These are 3v CR2 batteries (Lithium) and new from Amazon just ordered on July 12th. I don't know if they'll just keep reporting or not, even though they show low battery %, suppose I can leave them be and see how long they report in.
Leak sensors normally only need to report in a couple of times a day unless there is a water leak. I have a Zooz device that I use to monitor the level in a tank so the input valve will be closed when the tank is full. Thus. I expect the battery life to be shorter for that device than similar devices that only detect overflows and spills.
Since the battery life has been so short, you might check to see what the settings are in the driver. The device might be checking in more frequently than necessary.
Also make sure the device has a strong connection, either directly with the hub or through a repeater. If the connection is weak, the device may have to send multiple signals before one goes through.
