Litter Robot 3 Connect DFI issues, missing, blue flashing light, not working

Hi there,

You may want to read the following blog: https://community.robotshop.com/blog/show/how-to-install-the-litter-robot-connect-kit-new-version

This is a step-by-step guide to install the Upgrade Connect Kit to a regular Litter-Robot III.

You will read in the beginning of the guide that the Connected version is now equipped with a laser DFI sensor which has one board only.

Concerning the blue light:
The app uses an algorithm to estimate how full the unit is based off the number of times it normally has to cycle for the unit to be full. The unit does know when the drawer is totally full but anything before that is an estimation. Over time, once the app has compiled more data, the estimation will become more accurate. I would say everything is fine but to keep an eye on it over the next week or two.

How do I reset so the algorithm starts from no information at all?

I would presume that all the issues of drawer full after nearly every cycle has given bad data to the algorithm and therefore it is giving false positives all the time. Without a reset of this data it would be safe to assume that the problem will persist.

Iā€™m having the flashing blue light issue as well. This occurs even without the drawer inserted. Iā€™ve cleaned the lenses and everything around them twice now, but as soon as I power it on, the blue light flashes right away. If I press reset, as soon as it works once the blue light flashes again. Itā€™s been doing this since the first day I bought it. Can you help me?

This is beginning to sound like a design flaw. Has anyone heard back from RobotShop about this issue yet?

If your unit is still under warranty and/or was bought with RobotShop, let me know.

I will create an internal support ticket and take care of this situation.

I am currently experiencing this issue and was told my trouble ticket was closed and it would be converted to internal but I never received any emails or follow ups. Thatā€™s why I am in this thread.

I opened a support ticket and they told me that the learning algorithm will get better on itā€™s own. They confirmed that the new machine has only one sensor that is laser driven and will tell you when it is absolutely full, but that itā€™s the algorithm that needs to improve. This makes absolutely zero sense - how will it possibly get better when I canā€™t give it any accurate feed back? I emptied my drawer two days ago, pressed empty drawer on app and pressed reset button on unit. Works for two days and now it says itā€™s full - great, what do I do now? Tell it I emptied it when I donā€™t? Empty it early? Ideally I would be able to tell it ā€œNo, you are only 1/4 fullā€

Beyond frustratedā€¦

Iā€™m trying the below based on what some other LRC users have said.

Basically to improve/correct the data gathered by your litter robot you have to

  1. let it do its cycle once the cat has used it
  2. If you get a bin full notification, check the drawer.
    If itā€™s not full then press the reset button on the litter robot (not on the app)
  3. Repeat steps 1-2 until the bin is actually full
  4. Once the bin is actually full, press the ā€œreset gaugeā€ on the app and reset on the unit

So going by this, I think you can let the litter robot know that ā€œNo, itā€™s not actually full yet.ā€ By pressing the reset button on the unit and by not pressing the ā€œReset Gaugeā€ button on the app until you actually have a full bin.

Iā€™m trying this now and hopefully it will improve over the next few days.

Got my robot last week and I have the same problem :unamused:

I have the same problem as well, think I should have purchased the cheaper robot & just check every few days manually as I still have to check anyway which to be honest defeats the purpose of the app :see_no_evil::woman_shrugging:

Hi everyone,

Apologize for the delay.

I receive really interesting update from Litter-Robot.

To reset DFI sensor fault on a Connect Litter Robot please hold Reset button until the blue light blinks quickly. After that, it should come to solid blue light.
This should really fix the issue of the DFI.

@pjutras yes it resets it back to solid but every time now after my unit cycles it continues to flash as if full when not. I have to manually press the reset button after the cycle to stop the DFI flashing lightā€¦

I have done all the troubleshooting and I still get this. Just started happening in the last few days and Iā€™ve had this litter robot since November 2017.

Anything else I can do I guess besides pay for the $80 replacement kit?

Hey @Rutoy21,

If the troubleshooting doesnā€™t solve the issue, then DFI sensor should be replaced.

Are you still in warranty?

@igor_X no I bought it back in 2017.

So itā€™s odd that when I hit reset it resets fine itā€™s just that after the cycle process it indicates itā€™s full.

So essentially just a malfunctioning DFI circuit I guess?

Thatā€™s unfortunate. Almost been 3 years so I canā€™t complain, just odd how itā€™s out of nowhere.

Thanks for your reply.

Hi @Rutoy21,

Yes, we have seen this behavior before. DFI sensor failure is most common failure root cause for Litter Robot 3 Open Air.

Hi,

I have noticed that my DFI SENSOR is broken.
I have the Litter Robot III open air WiFi Connect.
It is still under warranty. How can I get a new sensor?

Best regards,

Pascal

Hi @PascalWoude!

How did you determine that the sensor is broken?

What is your order ID and a serial number of the robot?

Thank you.

Hi,

Can I send you a private message or mail?
This information should not be put in the open.

Best regards,

Pascal
