Hi @Grzegorz Mroz Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.
I am not sure what parameter needs to be entered in that particular field. The documentation does not provide much information on that. Have you tried sending the data using routing option? You can add a route to send data between modules on the IoT edge device. Try to add a route like the following
FROM /messages/modules/<your ASA module>/* INTO BrokeredEndpoint("/modules/<your local blob module>/inputs/temperature")
Give it a try and see if this works.
