What type battery does the smart things water sensor use? I just go an alert that my battery was down to 1%, but I am not at home to check it. Thanks.
LOL, same for me today.
They use a CR2.
BTW, I’ve had this sensor since Sep '16 and that was the original battery. It also took a bath when one of my tanks leaked. Sensor floated in an inch of water. I dried it off and it carried on with the same battery just fine until today.
I recently go the 1% battery message as well. I replaced the battery and within two days I am now getting the 1% battery life message again. The SmartThings app says it went down over the last several hours. Is my sensor working properly?
