circular dependency

[donaldta]

Oddly, I was able to get this running fine without errors a few days ago. However, now I can no longer see any devices connected to the monitor. When starting the app via "npm start" I see the following errors.

Error: connect EHOSTUNREACH 10.203.40.35:9999
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1146:16) {
  errno: -113,
  code: 'EHOSTUNREACH',
  syscall: 'connect',
  address: '10.203.40.35',
  port: 9999
}

I think there could have been some changes in npm/js that caused this. Tried doing an npm update and got the following message, "npm WARN deprecated core-js@2.6.12: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.". And while it updated some software, I still see the same error and symptom.

Unfortunately, I cannot use the pre-packaged binaries since the auto-discovery method does not work for me. I have to hard code the IP in the services/device-manager.js using the hack provided by Peter Robins' (probins) from another issue.

	let devClient = new Client();
	devClient.getDevice({ host: '10.203.40.35' })
	.then(device => registerPlug(device))
	.catch(err => console.log(err));

And today, it found the device.

No changes have been done since the last posting. Started it up this morning and to my surprise, it just started working again.

I'm going to leave this issue open in case the original author or someone else decides to address the "Accessing non-existent property {cmd} of module exports inside circular dependency" issues. Perhaps fixing the discovery process or even providing a way of legitimately adding devices manually.

Hey,
you may check out https://github.com/Xeroxxx/tplink-energy-monitor

We improved the current build form james and currently working (dev-v2.0 branch) on a complete remade and improved version.

FYI, I had the same problem of circular dependencies, but when I ran the Xeroxxx code, it worked fine.
