Nee-vo Command Line Sensor Broken?

Configuration

Has anyone using the Nee-vo command line sensor experienced it breaking recently?

command_line:
  - sensor:
      command: "curl -u <user>:<password> https://telematics.otodatanetwork.com:4432/v1.5/DataService.svc/GetAllDisplayPropaneDevices --header Content-Type:application/json"
      name: "Propane Tank Neevo 371"
      unique_id: propane_tank_371
      value_template: "{{ value_json[0].Level|float(0) * 2.4 if value_json[0].Level is defined else this.state }}"
      scan_interval: 14400
      state_class: measurement
      unit_of_measurement: "Gallons"

It was working fine for a long time but I just noticed that it is now returning “entity is non numeric.” Nothing is showing up in logs. Manually browsing to the site prompts for a login but returns HTTP 500 - which this may entirely be their server side or something needs to be changed in the curl argument. Speaking of which, I get nothing back on cml curl or even pings.

Anyone ran across this yet?

Add -v to the curl command, and show the output

Thanks for the reply. Please take a look.

Getting error 500 in my case as well

I am also getting error 500. It doesn’t look like the API has changed from what I can tell: https://telematics.otodatanetwork.com:4432/v1.5/DataService.svc/help

Same here. Stopped working a couple of days ago, and some playing around with Postman didn’t reveal anything more than the 500 errors. The help URL does say all the services updated “2024-10-04T21:56:31Z”. My Nee-Vo app on the phone is still working, but not really sure if it is updating because I only use my propane for supplemental heating and haven’t had to use it this season yet.

I was able to analyze the HTTP traffic of the iOS app and noticed the URL changed.

New URL: https://ws.otodatanetwork.com/neevoapp/v1/DataService.svc/GetAllDisplayPropaneDevices

Awesome job! That fixed it. Thanks for looking into this and figuring it out. How’d you figure it out in case this happens again? Wireshark?

Sorry for the delayed reply! Yeah, I used WireShark to capture the request.
