How to update multiple Characteristic value in the loop
Hi,

I have created accessory with multiple services in loop and want to automatically update its Characteristics in the background, but only first Characteristic of the loop is updated, here the code:
```
      for (let i = 0; i < this.qRelaysCount; i++) {
        this.enphaseServiceQrelay = new Service.enphaseQrelay('Q-Relay ' + this.qRelaysSerialNumber[i], 'enphaseServiceQrelay' + i);
        this.enphaseServiceQrelay.getCharacteristic(Characteristic.enphaseQrelayState)
          .onGet(async () => {
            const value = this.qRelaysRelay[i];
            if (!this.disableLogInfo) {
              this.log('Device: %s %s, qrelay: %s relay: %s', this.host, accessoryName, this.qRelaysSerialNumber[i], value ? 'Closed' : 'Open');
            }
            return value;
          });
        this.enphaseServiceQrelay.getCharacteristic(Characteristic.enphaseQrelayLinesCount)
          .onGet(async () => {
            const value = this.qRelaysLinesCount[i];
            if (!this.disableLogInfo) {
              this.log('Device: %s %s, qrelay: %s lines: %s', this.host, accessoryName, this.qRelaysSerialNumber[i], value);
            }
            return value;
          });
       accessory.addService(this.enphaseServiceQrelay);
 }
```

Here part of code which update the accessory Characteristics:
```
this.qRelaysRelay = new Array();
this.qRelaysLinesCount = new Array();
for (let i = 0; i < this.qRelaysCount; i++) {
            const relay = ENVOY_STATUS_CODE[inventory.data[2].devices[i].relay] || 'undefined';
            const linesCount = inventory.data[2].devices[i]['line-count'];

            if (this.enphaseServiceQrelay) {
              this.enphaseServiceQrelay
                .updateCharacteristic(Characteristic.enphaseQrelayState, relay)
                .updateCharacteristic(Characteristic.enphaseQrelayLinesCount, linesCount)
            }
            this.qRelaysRelay.push(relay);
            this.qRelaysLinesCount.push(linesCount);
        }
```

Thanks for any help.
