Unable to decrypt message on latest release #8

Joeboyc2 · 2019-09-08T00:13:27Z

Using the latest release i cant seem to get my robovac to work, (i previously had it working on firmware 1.1.1 but the vac updated itself :( and it stopped working so i have been waiting for this new version)

The error im getting is this:
2019-09-07 23:13:19 ERROR (MainThread) [custom_components.eufy_vacuum.tuya] 'utf-8' codec can't decode byte 0x95 in position 0: invalid start byte

The vac has been added to HA and the entity is showing, but i'm unable to trigger anything or see the state

The text was updated successfully, but these errors were encountered:

The most obvious issue i can see is the message saying: "failed: [Errno 104] Connection reset by peer" but im not sure why i would be getting that :(

Joeboyc2 · 2019-09-08T10:46:40Z

so it look like i had my "localkey" wrong, updating it to the one i found in the logcat i now get a different error:

Joeboyc2 · 2019-09-08T19:33:08Z

After doing some more testing I've found that the functions in the component do actually work (despite the errors in the log), it looks like the errors might be coming from the status requests as it shows 'error' in the component window

mitchellrj · 2019-09-08T19:55:38Z

The same status request gives you the battery percentage, which looks OK. The "error" status should only show if there is an error with the device itself - does the app show an error? like "bumper stuck", that kind of thing?

The logs do also show some errors decoding messages, so I'll leave this open to track that if other users encounter it too.

Joeboyc2 · 2019-09-08T20:30:25Z

oh thats odd as its not in an error state currently, its charging
but as everything else is working i'm happy with that, hopefully the error is something that can be ironed as its filling up my log lol

silviudc · 2019-12-06T19:15:30Z

I am having the same issue with a 15C Max, error status but the functions do work.
I am getting this in the logs:

And the same message above is failing to decrypt over and over.

Maybe the 15C Max has different functions/status compared to the 30C?
15C Max is model type T2128 vs T2118 for the 30C

silviudc · 2019-12-08T15:05:50Z

Just to mention the FW details on the eufyhome app: Wifi Version 1.1.2 and MCU Version 1.1.1

silviudc · 2019-12-20T15:47:08Z

Any chance to work together and get the error status issue resolved, I can provide assistance if needed.
Without that working I cannot get any automations to work

michelcve · 2020-03-20T15:07:31Z

@mitchellrj I can confirm that I have the utf-8 codec errors as well with my Robovac.

Any chance you could look into this?

cjazinski · 2020-04-24T14:42:02Z

@silviudc You get anywhere on this? I'm having the exact same behavior as you.

silviudc · 2020-04-24T17:36:17Z

Yes I did a reset on the vacuum, re-added it to HA and it's been fine ever since.
Too bad the integration doesn't have the 30 minute and edge modes options but it is better than nothing :)

cjazinski · 2020-04-24T17:48:14Z

Did you modify the tuya.py version number as I've seen floating around from 3,3 to 3,1? If I do that I see a different error (below). But still no functionality :( I've removed from the app and hard reset the device (holding down power until beep). What firmwares are you on? I'm running Wifi - 1.1.3and MCU 1.1.1

Have a look at this PR: home-assistant/core#25483

I included those 2 changes in HA and edge mode works. I personally do not use the 30 min one, although could probably be added based on the PR above.

Works on my RoboVac 30c

I've tried resetting and readding the device (a EUFY 15C MAX). and ive checked the keys atre correct multiple times

Hey, I still have this issue on one of my vacs, its odd becuase I have 2 of the same model, running the same firmware, only one of them gives me the errors, but its does control correctly regardless so I just ignore them now

I have the same issue. Any updates on how to resolve this? Thanks

I was having this issue - what I did to fix it was to cause an error with the vacuum by picking it up when it was vacuuming, then going into the Eufy app on my phone and clearing the error there. This had the effect of fixing the 'error' status in Home Assistant.

inijman · 2023-01-15T11:39:21Z

same issue here with G30. Forcing an error and fixing in the app did not resolve it.
