UnhandledPromiseRejectionWarning / No Response

[raulfunkie]

Getting this error while running homebridge in debug mode to see what's making it not recognize the Robovac as a device. The "devices" show on Home App (Switch to Find and Fan for Vacuum) but they're always on a "No Response" status.

Config File

    {
      "accessory": "Eufy RoboVac",
      "name": "Robotina",
      "ip": "192.168.6.248",
      "deviceId": "60608308ecfabc982fba",
      "localKey": "b32c7a55c9f1f301"
    }

I've set a reservation for the vacuum on my router to have this specific IP and I got the keys using the guide provided by mitchellrj using adb and logcat.

Any ideas on what could be happening?

Update 1

I found that I made a mistake using the wrong IP address (it should've been 192.168.7.248 not '6').

I updated that on my config.json:

    {
      "accessory": "Eufy RoboVac",
      "name": "Robotina",
      "ip": "192.168.7.248",
      "deviceId": "60608308ecfabc982fba",
      "localKey": "b32c7a55c9f1f301"
    }

and I'm now getting this error:

I am also getting this exception:

In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

But I have both the correct IP address and the localKey values (from the JSON captured payload). My RoboVac is 30c and I believe I have the latest firmware. 1.1.3 Wifi and 1.1.4 MCU according to the RoboVac app.

I also tried eufy-robovac project demo and unfortunately it does not work. So is this code still working for people with the latest Eufy firmware updates?

OK, it looks like there was a update which broken this code but the python based eufy_robovac project seems to have fix it in this branch

There demo code here works with my Robovac 30c

Did you get this working on Homebridge? Cause I couldn't get it working and I have the same exact error ( Error: find() timed out. Is the device powered on and the ID or IP correct?)

EDIT: found a solution. I did build eufy-robovac myself and moved it to _homebridge-eufy-robovac/nodemodules/eufy-robovac.

If someone has the same problem you can replace homebridge-eufy-robovac/dist/index.js with this: https://pastebin.com/evYiCzqb

@crazywako would you mind sharing your whole homebridge-eufy-robovac folder? I can't get it to work. I replaced the file mentioned above but still no dice on the Home app. :(

@crazywako Mind doing a pull request or sharing your changes to either https://github.com/joshstrange/homebridge-eufy-robovac or https://github.com/joshstrange/eufy-robovac so that we can get this working without having to use a transpired index.js?
