How do I "down"grade a HACS-loaded custom integration?

I implemented Home Assistant so as to be able to control my GivEnergy system, which I’ve been doing using the GivEnergy Local integration.

Which since an upgrade several days ago has been broken, so I’m having to control my system manually.

SO … how do I revert to running an earlier, working, version?

Assuming you are not using the experimental interface:

  1. Click on the integration card in HACS.
  2. Click on the three dots icon top right of the page.
  3. Select Redownload.
  4. Choose the version you want from the dropdown list.
  5. Click Download.

Yes, it was knowing to click on the three dots on what looks like a page of documentation that I was missing. Thanks.
