HomeAssistant - PowerCable MQTTflex configuration update

When integrating with recent versions of Home Assistant, it is required to have clientId parameter set in NETIO device MQTT-flex configuration. The parameter is optional for the device, however it is needed for successful integration with Home Assistant. Without the parameter supplied, it throws the following authorization error:

• 1613745264: New connection from 192.168.1.211 on port 1883.
• [ERROR] Auth error with f476a2e46eb
