I got out my two timers this spring after using them last year with no problem but one keeps showing low battery and not allowing me to use it. I changed the batteries in both timers as soon as I got them out again. Both timers have Firmware Version 0041, and my WiFi Hub has Firmware Version 0030. I am full able to use one with no issues but the other one is giving me quite a bit of frustration. I tried connecting via bluetooth directly to the timer but that did not update the battery life either. I also tried removing the device from my account and re-adding it to no avail. Please help.
