WiFi wireless issues upon restoring wifi connection

    I agree that it doesn't seem to reconnect appropriately. I've never had the patience to swipe around too much. I typically reboot it and see what happens.

    I have the same exact issue.   But it isn't always due to the router resetting. Initially my wireless connection was pretty stable but increasingly I need to go outside, and hit home and the unit reconnects with no problems.  Perhaps the programmers could include an option to automatically reinitialize the wireless connection at a specified time each day . This will at least allow the unit to update its weather once a day .

    My HD-12 fails to reconnect properly to the WiFi network every time the WiFi goes down due to power outage, manual power recycle, firmware update, etc of the wireless router.  After the router powers back up and other wireless devices around the house reconnect, the HD-12 is stuck in a frozen state and is shown as offline on the iOS app.  Login on my.rainmachine.com is rejected with wrong password message even though correctly entered.

    To resolve, I must manually reconnect it to the appropriate WiFi SSID on the HD-12 device itself, requiring travel to the site.  This is very annoying and for me defeats the purpose of remote access.

    I do have multiple WiFi SSID's at this location.  But why doesn't the HD-12 just automatically reconnect to the SSID it was on before the outage, or any SSID for that matter?

    I am on latest firmware and iOS app version.

    Do you need to specifically reconnect HD-12 by going to Settings > System > WIFI or it just reconnects when you touch the screen ? Does it reconnect if you reboot HD-12 ? Are there any repeaters on your setup ?

    We are going to release a beta firmware soon that has an forceful reconnect in the case the system doesn't recover itself.

    What you could try with current version:

    1. Settings > System > Display > Check "Keep screen on but dim the display"

    2. Forget all networks that you have previously connected. Connect to the chosen network.

    I forgot to mention in the post above, that when the HD-12 is stuck in this offline frozen state, there are repeated cycles of notifications sent to my iPhone of the RM being offline for 30 minutes, followed by a notification that the RM is back online.  These notification cycles repeat at random times perhaps 10 or 12 times per day.  The reconnection notification is usually within an hour of the 30 minute disconnection notice.

    Even just after the notification occurs that the RM is back online, it really isn't and can't be reached either through the iOS app or my.rainmachine.com, as I described above.

    Nicholas, thanks for the steps to try in your post above.  I'll be trying to get my HD-12 back online later this morning.  When do you think the pending firmware will be released to avoid this problem?

    Maybe in your case there is really a signal issue as RainMachine might connect and lose connection after a while. Anything you can do to improve signal like putting and extender USB cable and put the WIFI adapter closer to router ?

    Thanks, Nicholas.  I don't think it is a signal issue, for a couple of reasons.

    First, even immediately after the notice of reconnection is issued, the RM still can't be accessed remotely, either by iOS app or web login.

    Second, to get a strong WiFi signal to the RM (located outdoors), I have installed a wireless access point inside the house exterior wall at a spot that is just 3 feet (through the wall) from the RM.  When the RM is actually connected, it is just fine with this arrangement, with the RM indicating a WiFi signal of -45dBm or so.  The problem is only that when the WiFi signal goes down for any reason and then is restored, the RM fails to reconnect.

    If I recall correctly, the last time this happened, the RM did spring to life (and possibly reconnected) as soon as I touched the display.  So your mention of the display sleep mode being potentially involved gives me some hope.  And, I will also try your suggestion to have the RM "forget" extraneous WiFi SSID's that it may have connected to in the past.

    But it strikes me that, overall, the RM firmware needs to be more robust as it relates to reconnection after a power loss and I'm hopeful that the beta firmware that you mentioned is a true solution.  Is that beta firmware available to test?

    This would be interesting to have more logs, after this issues happens could you please try to connect locally and check the status of "Remote access" ? This is shown on dashboard on web interface and on Settings > Remote Access on mobile apps. It should display. I will also ask the devops to investigate your connection log.

    Not yet, we are adding some WIFI drivers for dual-band/high-gain adapters that must pass some tests first, but it's close to being released.

    I have someone going to this location in a couple of hours or so to do the reconnection.  So the logs will reflect that at that time.  I will not be there myself for a week.

    Nicholas, my RainMachine HD-12 is now back online and currently running Zones for the next 3 hours.

    The RM was in a frozen, offline state as descibed in earlier posts.  The wrench icon was flashing.  The main portion of the screen was off.  At your suggestion, the main screen was touched first and came to life.  Nothing changed on my remote iOS app even after waiting about 30 seconds.  Then, the wrench icon was touched to get to Settings.  While navigating the Settings, but before making any changes to WiFi or any other settings, the RM changed to online status on my remote iOS app.  The RM was shown as being connected to it's usual WiFi SSID, with a signal strength of -54dBm.  I tested irrigation on one zone by triggering it on my remote iPhone and it worked.  In the Display settings, the checkmark was made manually for the setting to dim the display after 2 minutes.  A full Program was then selected to run via the iOS app.

    Does all of this indicate that the problem on restoring a lost WiFi connection has to do with the display going off?

    Nicholas, I see the newest beta has support for 3rd party wifi adapters. I currently have this issue wth my HD12 where it drops wifi connectivity and have to wake the screen for it to reconnect. If I leave the screen active like above it actually takes HD12 longer to reconnect to wifi when I manually try reconnect it. I'd like to try a third part high gain antenna to see if that would help remedy the issue. Do you have a list of supported wifi adapters?

    Hi Cole,

    First try the new beta without a new adapter, we improved the WIFI reconnect methods. As for highgain we have it running with this dual-band/high-gain module: 

    https://www.amazon.com/TP-Link-Archer-T9UH-Wireless-network/dp/B01GE9QS0G/ref=sr_1_1?ie=UTF8&qid=1529078512&sr=8-1&keywords=Archer+T9UH&dpID=31mvs6jQEaL&preST=_SY300_QL70_&dpSrc=srch

    P.S. The new beta .944 is now closed as it reached the number of users per day allowed, it will resume on 2018-06-19.

    Per the advice above, I had set my HD-12 to dim the screen but not turn off.  I also had it "forget" the wireless networks other than the currently used SSID.  Today, my cable modem/router went offline unexpectedly and was off for several hours before it was rebooted and came back online.

    Just as before, the HD-12 remained offline even hours after the network wifi was back up.  I went to the RM and pressed on the flashing wrench.  I waited for it to come back online, but it didn't.  I had to go into the RM's wifi settings and manually touch the connect button for the correct SSID.  The RM then connected.

    I too am hoping to try the beta firmware .944 when available, as the previous suggestions did not seem to work.

    Same issue with HD-12 and Negear Orbi.  It's drops (or sleeps) WIFI so often that I set up a Z-Wave power outlet to allow re-booting the HD-12 remotely when it is offline and I am out of town.  None of the other solutions have worked.

    Jim Weston, great idea!  I am going to do the same.

    Is there any difference between pressing Reboot in the RM GUI vs. just pulling the plug (in effect) by toggling the AC power via a smart plug?  Does pulling and reinserting the plug (or toggling AC power with a smart plug) risk doing any damage to the RM?

    Does the RM always properly connect to wifi when AC power is toggled off and on?

    RM always reconnects to WIFI after toggling power via ZWave outlet, not aware of any potential for damage.  Easy fix until software update fixes the issue.
