Hi all,

I create a thing and use MQTT to receive data. The Connection is true.

 

I create a property to receive the information, but only when i click Refresh Properties i can see the info received, How can autorefresh this property without click Refresh Properties.

 

Then i create a subscription that save message received in other property, and doesn´t work, maybe doesn't detect that Property "Prueba" changed,

 

Please i need help.

Hi @juancmaldo

 

You cannot autorefresh this page. It was design just for preview purposes, so it has no ability to refresh it automatically. You can bind this data in mashup and see it with autorefresh there.

 

If you want to save message from one property to another one I can propose local-binding. It is code-less solution for your problem:

Check if your property has DataChange defined as "Value" or "Always". If it is "Never" it will not trigger a DataChange event.

 

Best,

Adam
