Shelly cover calibration automation using device API and position restoration

After a while, covers that use time or consumption-based positioning start to drift from their calibrated state. Therefore, I searched for a way to calibrate my covers without the need for manual intervention.

I came up with the below automation which takes the following actions:

  1. Stores the current state of all covers for later restoration to aux input text entities.
  2. Call Shelly API using REST according to Shelly’s API spec.
  3. Wait for 10 minutes for calibration to complete.
  4. Restore previous covers state.

This automation is set to trigger once a month but you can obviously change it to your liking.
You should keep in mind that for this to work you must take note of your Shelly 2PM module IP addresses and update it in the cover_ip_map.

Any questions or suggestions are welcome.
