Hi!
How can I set the frequency of sending MQTT messages from Shelly PRO 3EM devices? 
Currently, messages are sent between 1 second and 15 seconds, which generates a very large amount of data. 
On the one hand, a data transmission frequency of 1 minute would be sufficient for me, on the other hand, the data is transmitted via GSM router, so it is important to keep the data volume as low as possible.
What is the solution?
Unfortunately, the MQTT solution offered online for other Shelly devices did not work for PRO 3EM.
The attached file contains some specific data. Column B shows the name of the measurement and column A the time of the message.
