I’ve been having the same problem. All devices are on firmware 32. But some of the units just don’t water when they are supposed to. I keep having to look at the logs to see the gaps.
I see the advice to switch to Bluetooth but really would prefer not to. In every other product I use, WiFi is much more reliable and that’s one reason I chose this product — because of the WiFi option.
Is there a known bug with WiFi? Or is there a fundamental problem with how it works that makes Bluetooth a better choice for this use?
