All is in the title.
Get list of thins you want to chech whether that is running or not...
try execute above code, it will return thing name. else it will return some error.
It was not what i expected. I have several thousand of dynamic things with interactions. I expected something like "System is ready". Seems the system should know when he finished to create all things present in its database, it will be easier for him to create a global event.
There is a subsystem service called: GetEntityUsageReport which might be close to what you need?
It shows enabled/disabled entities, so not technically running or not.
