A client for an insecure HAP-NodeJS instance. Provides a Typescript based interface based on the homekit accessory protocol, allowing the creation of clients able to connect to and control Homebridge devices.
# API
```
const { HapClient } = require('@homebridge/hap-client');
this.hapClient = new HapClient({
config: { debug: true },
pin: config.username,
logger: this.log,
});
this.monitor = await this.hapClient.monitorCharacteristics(services?: ServiceType[]); // Creates event monitors for all event capabable Homebridge services. If a list of services is, this list is used rather than all
```
## hap-client Events
```
this.hapClient.on('instance-discovered', this.instanceDiscovered(instance: HapInstance)); // Emitted during discovery for each HB instance discovered
this.hapClient.on('instance-configuration-changed', this.instanceChanged(instance: HapInstance)); // Emitted during discovery for each HB instance change
this.hapClient.on('discovery-terminated', this.discoveryTerminated()); // Instance discovery was terminated
this.hapClient.on('discovery-ended', this.discoveryEnded()); // Emitted when discovery has ended ( 60 Seconds )
this.monitor.on('service-update', this.serviceUpdate(services)); // Emitted when a characteristic change is received from a homebridge service
this.monitor.on('monitor-close', this.monitorClose(instance, hadError)); // Emitted when the connection to a homebridge service is closed ( likely a restart )
this.monitor.on('monitor-error', this.monitorError(instance, error)); // Emitted when the connection to a homebridge service has an error ( likely a restart )
this.monitor.on('monitor-refresh', this.monitorRefresh(instance, error)); // Emitted when the connection to a homebridge instance has been refreshed ( Triggered when an instance is discovered and its port, configuration number or name has changed)
