This is the same tool from: Github Pages Please refer to that repository for all the instructions. Here I will only document the MacOS specific instructions.
You need Python 3.6 - This is what I have on my Mac
You only need the MacApp/SonoffToolMac.app downloaded to you Mac. Once that is done, there are two possible ways of openning the applications.
- The simplest being to just open the app like any normal app (double tap/click)
- If option 1 does not work, right click the app, then select "Show Package Contents"
- Select Contents
- Select MacOS
- Open SonoffToolMac
