For a a few months I am getting a lot of this errors: (a lot of emails)

I assume a device is deleted, but the app is still doing all the actions (capabilities, timers, etc.)

In my code I have added, but without success

> onDeleted() {  
> clearTimeout(this.PollingTimeOut);  
> clearTimeout(this.StartPolling);  
> this.homey.clearInterval(this);  
> this.homey.clearTimeout(this);

You have some strange things in your code:

```auto
clearTimeout(this.PollingTimeOut);
this.PollingTimeOut();

```

You’re clearing a timeout that has the same name as a method? That can’t be right.

A timer is the result of a call to `setTimeout/setInterval`, and that’s what you need to clear:

```auto
this.PollingTimer = this.homey.setTimeout(...);
...
this.homey.clearTimeout(this.PollingTimer);

```

Also this:

```auto
clearTimeout(this.PollingTimeOut);
clearTimeout(this.StartPolling);
this.homey.clearInterval(this);
this.homey.clearTimeout(this);

```

You shouldn’t be using `clearTimeout` at all, only `this.homey.clearTimeout` (same for `clearInterval`).
