3em ampere log

Hi, I bought Shelly 3em and connect to three phase heater. I would like to know the maximum amps, which heater consumed. Log file does not contain this data.

1. Is it possible to add average and maximum amp and voltage to the existing log data for each minute?

2. Is there any other way, to log this data to file or database? Perhaps raspberry pi? Data can be acquired with periodic http://ip/status commands. Does anyone already use that kind solution?

Thanks

Can you recommend any and point pe to tutorials, please?

Hi,

I'm not familiar with Homematic. It will take to much time to learn it.

My preferences are:

1. Raspberry pi

2. 1 minute data sampling from Shelly 3em (url://IP/status) to get at least voltage and current

3. Data can be stored into mySql data base or csv file, which should be easy export. No fancy GUI just link to download file or url to mySql query editor

4. Simple installation and setup with tutorial would be appreciated.

No cloud requred, only LAN communication.

Thanks.
