Start Zigbee2mqtt addon by automation

Hi there.
I try to find a solution how to start zigbee2mqtt addon by Automation.

Situation:
I have [ZigStar GW] configured on (http://192.168.1.220/)
for some reasons the LAN stick can be unavailable for some time.
As a result the addon Zigbee2MQTT stop to work.
and i need to restart HA or run it through interface.

is it possible to create Automation which constantly check Zigbee2MQTT status. in case the plugin stop work, does it’s start afther certain period of time, or by condition based on ZigStar GW availability?

Thank you
