I have the same issue …

I´ve runned bellow commands

$ ionic plugin add cordova-plugin-dbmeter
$ npm install --save @ionic-native/db-meter

and used like this

import { DBMeter } from '@ionic-native/db-meter';

constructor(private dbMeter: DBMeter) { }

...


// Start listening
let subscription = this.dbMeter.start().subscribe(
  data => console.log(data)
);

and i get same error as @yoke92 …

@yoke92 …

I found the solution …
just add providers like this:

@Component({
  selector: 'page-dbmeter',
  templateUrl: 'dbmeter.html',
  providers: [DBMeter]
})

and this …

  ionViewDidLoad() {
    console.log('ionViewDidLoad DbmeterPage');

    let timer = setInterval(() => {
      // Start listening
      let subscription = this.dbMeter.start().subscribe(
          data => this.currentAmplitude = data
      );
    }, 100);

  }

I’m new in IONIC and want to build a DB meter app. Can I have you code as example?
