Gen 2 frequently falls offline after firmware update


I started having the same problem a couple of weeks ago after turning off stand-by mode (it was the first time I’d ever used stand-by mode). The device has worked great for as long as I’ve had it. I read through this thread and saw the note about a possible fix a couple of nights ago. However, this morning I received the notification that my Rachio had been offline for 24 hours again. Apparently it went offline about 90 minutes after I had last power-cycled it to bring it back online from the previous day. Here’s a rundown of the incidents:

11/14 4:10 PM - Standby Mode OFF
11/21 3:00 PM - Controller Offline (first occurrence)
11/21 4:18 PM - Power Cycle (manually unplugged)
11/22 11:00 PM - Controller Offline
11/24 1:56 PM - Power Cycle
11/24 3:46 PM - Power Cycle
11/24 4:21 PM - Power Cycle
11/25 11:09 PM - Power Cycle
11/26 12:57 AM - Power Cycle
11/27 2:00 AM - Controller Offline
11/27 6:34 AM - Power Cycle (manually unplugged)
11/28 8:00 AM - Controller Offline

I also ran the RouteThis test. My key is K4XG8QKG.

Hope that helps find a fix.


Changed my home router setup to be two distinct networks instead of two AP’s on the same SSID. Rachio seemed to like this as it hasn’t disconnected for a few days. Took the rachio off standby for a few minutes, put it back on standby and then reconfigured my network back to two AP’s on the same SSID. Rachio disconnected again sometime today and will require a power cycle when I get back home.


Glad the team found something significant with Gen2 & V3 firmware causing the controller to crash.

Just adding another data point, my controller stayed online (maybe went offline, but recovered automatically) Tues, but it went offline again in the crashed state Wed. I needed to power cycle it manually.

Is Rain Skip supposed to work even if the controller was offline for a few days? I expect no watering for the next several days.

Thanks, yuki


@franz Nothing. I’m off line again

Rachio Gen 2 keeps going offline lately

My Gen 2 went offline last night and I restarted it this morning at 5:22am using the Rachio troubleshooting directions and as of now it has power cycled at 8:02am and 9:11am but is still online. So, I’m not seeing any improvement in falling offline since the “new calendars” were released on Nov. 27? My Rachio shows firmware version iro2-firmware-5-109 and My Route This code is T77U8S3F.


Off line again! Off line Monday, off line this morning and off line again this afternoon.


Team Rachio, thanks for your patience.

We hope to push a firmware release out tomorrow to address this issue. It’s been incredibly difficult to track down and the team has been working around the clock (literally :slight_smile: ) to identify and try to resolve. I’ll post here when the firmware is pushed to the Gen 2 controllers.

Thanks again for your patience.


Rachio Gen2 firmware upgrade
Rachio Gen 2 keeps going offline lately

Yesterday afternoon after I got it back on line I saw the firmware update (iro2-firmware-5-109) and applied it. Experienced two more power cycles yesterday after that and this morning it was off-line again. Ugh!

And… isn’t there anyway that you can save the Wifi settings so I don’t have to reenter everything everytime?


We are rolling out new firmware to controllers to try and resolve this issue.

The new firmware version is iro2-firmware-5-115.

I’ve had the engineering team update all the controllers on this thread.

If you don’t see this version on the Technical Info screen and want to get it directly, just make sure you are on the same WiFi network as the controller and a button should appear (mobile only) that allows for a direct firmware update.

We are rolling firmware out to a small number of controllers today and will roll out to all remaining controllers next week.

Thanks again for your patience.


Gen 2 devices don't stay connected to Wifi

I got the update. I will monitor the controller state carefully over the weekend.

Thanks, yuki


Thanks @yukitz75, please let us know if you see any issues and have a great weekend.



I’m guessing you have them, but I’m really struggling to find any release notes on this new firmware. Can you please point me in the right direction? I’d greatly appreciate it!


@franz power cycled mine today will report back if anything occurs. Thanks for the hard work!


The new firmware update is working great so far. The last power cycle event in my controller history is from Thurs morning. I am guessing what was caused by the firmware update.

Since the update, I have not seen any offline state reported by the Rachio app on my phone. The controller has been at full-bars throughout the weekend. I think the issue has been resolved with the new update.


@yukitz75 That’s great news, the team is continuing to review but feels like we have resolved the core issue.



All Gen 2 controllers have been updated with new firmware. :smile:



My controller has been fine for several days as well. Seems to be fixed!


Several days since I got the -115 update, and all appears back to normal. Thanks, Rachio. This situation was handled promptly, and the level of communication and transparency from @Franz was excellent. Nice recovery.


Yep, me too…all of it. Had perfect stability for years, then suddenly these crashes that required a power cycle to fix. I had to do one just hours before franz posted about the firmware update. Since then, it’s been stable…I’ll come back and reply again if that changes.


…and it looks like after receiving the -115 update I’m also back to the stability I’ve been used to. Ditto the thanks to @Franz and the development team for getting that done.
