This is Fred, Karen’s husband. So yeah, ping is only returning 25% to 75% of the packets (sets of 4 pings). Never 100%. So lots of packet loss. And as Karen said, ping has no packet loss against the router’s IP. A browser on the laptop or tablet can’t even load the main page off the OpenSprinkler device. When using the Android mobile app, we keep getting the message “Check device password and try again.” We disabled requiring the password, but are still getting the same message the majority of the time. Could this just be a side effect of packet loss? Is it possible we just got a bad unit? On a positive note, while extremely intermittent, she has been able to turn sprinklers on and off using the mobile app. Thank you for any help.
