Shelly 3EM downloader and plotter

Downloading data

To download data and store it on an SFTP server, run the following command:

docker run --rm -it \
  -v ~/.ssh/id_rsa:/mnt/id_rsa \
  ghcr.io/soerface/power-plot \
  sftp://username@host:22/home/path/ \
  --host 192.168.178.99 \
  --download-only \
  --ssh-key-path /mnt/id_rsa 

It's recommended to do this daily to get the best resolution of your data (1 minute, after one or two days the resolution will be reduced to 10 minutes).

Plotting data

This example plots data from a directory that needs to be mounted into the container. Not all options here are required; please check --help for more information.

docker run --rm -it \
  -v ~/data/input:/mnt/input \
  -v ~/data/output:/mnt/output \
  ghcr.io/soerface/power-plot \
  /mnt/input/ \
  --dark-theme \
  --output /mnt/output/plot.svg \
  --from "2024-05-08" \
  --to "2024-05-10 12:00" \
  --sample-rate "1h" \
  --plot-phases
