    I installed it in june, and it has been working fine until this week, where it suddenly loses connectivity. The ip still shows on the display, but i can’t ping it. (It is connected by ethernet directly to my router).

    I never did any software updates, upgrades or tinkering. The only relevant setting was to set it up for static ip instead of dhcp. I don’t have other devices hitting the same ip.

    After powercycling it comes back, but it disconnects again from the lan a few minutes later. If a valve is active it keeps going. The leds on the side of the ethernet port keep blinking.

    We only use it manually to turn valves on and off. Didn’t set any programs.

    I’m at a loss on why it suddenly started doing this, since there hasn’t been any hardware or software change. The WAF is going down dangerously.

    Any assistance will be appreciated.

    When it loses connectivity, could you check the Ethernet jack on OpenSprinkler: there is a green LED and orange LED. The green LED should be on constantly and orange LED blinks occasionally. If the green LED is not on at all, that indicates a hardware or wire connection issue. In any case, you can submit a support ticket and we can arrange to send you a replacement unit to see if it fixes the problem.

    I just had this happen last night. My unit went offline and since it was under my house I waited and 30 minutes later it was back online.

    The firmware has a re-connect feature, where it detects connectivity to the router every few minutes. If it loses connection to the router for several times in a row, it will re-establish network connection. If after 24 hours it still doesn’t connect, it will automatically restart itself (but will only do so when no program is running) essentially performing a power cycle.

    I seem to be experiencing similar intermittent drop outs of my AC version controller. It’s powered from a GFCI outlet, which very occasionally trips. This happened whilst we were away and I missed 3 days of watering, so I set up notifications in my HomeSeer home automation system to send me Pushover messages when the OS controller device goes offline. I quickly discovered that it was going offline relatively frequently when the GFCI was still live – the GFCI hasn’t tripped since we were away in mid August. I added another notification to tell me when the controller comes back online and for how long it’s been offline.

    It’s dropping out about 5-7 times a day and reconnecting after ~20mins each time.

    I haven’t been home and awake when it’s dropped out yet, so haven’t been able to check the controller display and the ethernet port light activity, but I should be able to see that tonight.

    I have been using uptimerobot.com to watch my unit and the outage behavior has not come back since my initial post…

    rhos, do you have another power source and wall adapter to test?

    Hi Patrick

    Yes, I will test with a different circuit and power supply over the weekend

    Thanks

    So, I was able to try a different power supply and circuit and the OS Controller is still going unreachable multiple times a day. It is hard wired and I do see a steady green and flashing orange RJ45 lights even when it’s unreachable from the Web UI or phone app. I have this on static IP and I have no IP conflicts. Also the screen is still active and the buttons produce the expected results when pressed. Resetting the device brings it online as soon as it’s booted up.

    Is there anything else that I can test – maybe check for errors at the device somehow with a combination of button presses?

    Thanks

    What about utilizing a DHCP address for the time being to see if the network disconnections still occur.

    Beyond potential addressing issues the only other thing I can think is there may be something wrong with the switch port, patch cable, or cable run that you are using.

    An easy way to check all of these at once and either confirm it is the controller or rule it out would be to get another network device of any kind, set it to the same static address and plug it into the same patch cable.

    If the network disconnections occur on this other device it is either:
    -Network switch
    -Patch cable/cable run
    -Network addressing

    If the network disconnections stop then I would say the OpenSprinkler controller is possibly bad.

    I had the same problem with old tp-link switch but after changing switch is ok. Another reason may be overheating the ENC28J60 chip Tray put (glue) on it some metal plate or small heat sink.

    I am experiencing these exact same symptoms all of the sudden.
    – I have hardware version 2.3
    – I am running firmware 2.1.6, which i upgraded to 2.1.7 to hopefully resolve the issue. Symptoms persist.
    – My upgrade inherently performed a factory reset to eliminate bad or corrupt settings
    – I see a steady green light with intermittent orange on the OpenSprinkler network cable adapter
    – Right after a power cycle it works for no more than 10 minutes before i cannot connect to it anymore
    – I had it connected to a TP-Link switch (not the same model as listed above), but I connected directly to my router and am having the same issue
    – I tried two other IP addresses and both exhibited the same symptoms

    I don’t know what else to try for troubleshooting and this thread makes me skeptical that it may be a hardware defect. Has anyone successfully resolved this issue?

    Could you describe the symptoms? How did you detect that the network goes out? Do you use a software to periodically ping the device thus finding the network goes out?

    What occurs when my unit goes down is the device itself goes offline, no ICMP or HTTP. The sprinklers still run (if it goes down while they are scheduled), then the page comes back up after 1-15 minutes. See the attached log. I am using UpTimeRobot.com to query the HTTP page for TCP200.

    I am using openhab, which checks for running status every 5 minutes on the OpenSprinkler API. Also, i have shut that down and if i just open the OS web UI and leave it up for a few minutes, it will eventually display No Network at the bottom of the screen. I can’t tell you the exact frequency, but i can say it is a lot more frequent than Patrick’s.

    I am seeing this same issue (new unit purchased this year). Will randomly lose connectivity for ~2-25 minutes then come back. I have a device that checks “heartbeat” of all devices like the user above.

    When it is offline i have checked the device – the display is powered on as normal and the Ethernet jack shows solid connection (green) and activity. But not able to connect by http.

    Has there been a cause found / fix found for this? I can post logs from my network uptime device if helpful.
