Has anyone found a modification to make to prevent the internal flooding? Also does anyone have a picture/video of the internal flooding in action? I have replaced two timers due to this and want to install this third with some preventive measures. There are no leaks from my spigot and other non-smart hose timers have worked great so I am chucking this up to a design flaw.

Merry Christmas @franz I love this product but I am experiencing the same exact challenge, even with the battery door is properly closed and secured. Despite this, moisture is consistently found inside the battery compartment.
It appears that the battery door seal weakens over time, allowing water intrusion during normal outdoor exposure (rain or irrigation). This has resulted in repeated battery failures and renders the device unreliable for its intended use. This issue appears to be related to a sealing or housing defect.

I have the same problem. I frequently clean the rust and reset. Usually works. It’s a real problem when I am out of town for a while. Today I cleaned the valve and the light doesn’t come on and therefore pairing doesn’t work.

Mine looks like this too. I have had some success cleaning with vinegar and soda but it has now quit completely and won’t light up or reset.

I had a similar problem with one of my units. I assumed user error so I just bought a replacement. Unfortunately, at the end of last summer, the two I had purchased that season were also rusted with a corroded battery.

Welp.. It looks like I’m also suffering the leaky battery issue. Is there anything that can be done, or should I just buy a different device? Both of my units crapped out this year.
