Does the 3EM log peak power?

I have seen some screenshots of the 3EM app, and clearly it logs energyconsumption and it can show the live power draw.

But I am interested in history of peak power usage.

Is it correct that I can only derive 1 minute peak numbers because of 1 minute energy consumption resolution in the logging?

Or does it actually log peak power usage to?

Are there also triggers/events to be set when certain power or current levels are exceeded?

Thanks in advance

Well I can partly answer my question about the trigger/events.

The 3EM API lists under actions an over_power_url to be invoked at a user defined threshold.

So that at least is helpful, I can give an alarm and do some action, like shutting things off.

And I can also use it for logging, although it is a bit crude.

On the log file I find this:

Shelly 3EM: /emeter/{index}/em_data.csv

This provides an export of the data gathered by the device. For each measurement channel, a CSV file is generated with the following columns:

• Date/time UTC
• Active energy Wh
• Returned energy Wh

This will always contain data for the entire time range stored on the device.

But it doesn't say the interval. I read somewhere that this interval is 1 minute for the first 24 hour and becomes less after that?
