Thanks @ashvayka Also consider, please, such improvements for upcoming custom events (https://github.com/thingsboard/thingsboard/issues/10029)

[In TB terms](https://thingsboard.io/docs/user-guide/entities-and-relations/), there is no relations (Contains, Manages or some other) between tenant and devices. To resolve ownership of a device TB uses tenantId, ownerId and/or customerId. Of course,...

Use custom action ``` widgetContext.stateController.openState('your_state_id') // or widgetContext.stateController.openState('your_state_id', stateParamsObj) ```

Right. Here is how navigation to another dashboard is implemented inside TB UI https://github.com/thingsboard/thingsboard/blob/master/ui-ngx/src/app/modules/home/components/widget/widget.component.ts#L1070

Not sure if it is proper way, but it works `msg.object.length == null`

[maybe this will help](https://thingsboard.io/docs/user-guide/rule-engine-2-0/overview/)

All API calls are asynchronous

Don't know. Honestly, you want too lot from this widget. There is entities hierarchy widget and finally you can create your own custom widget.
