Hello,
I am using a Sonoff ZBminiR2. Now I have a strange issue. The Sonoff switch works fine with a physical switch. I can turn the light on and off with it. I can also turn the light on and off via HA.
But now comes the issue. If I turn on the light via an automation, I can no longer control the light with the physical switch, only with HA. I have to turn the light off again via an automation first. Then it works again.
Does anyone have any idea what this could be?
Welcome to the forum, Frank 
- Make sure you have set the ZBmini R2 to be used with a rocker switch (if your manual switch is a rocker switch). Else make sure to set the ZBmini R2 to push button switch (Momentary Push-Button switch) mode.
To change the mode for the ZBmini R2 short press the button to the upper right 3 times until the green indicator flashes 3 time quickly. Repeat if you want to change the mode back to the former state.
- Make sure you have wired the ZBmini R2 correctly:
If the above still does not help please show us the automation you have coded.
I have tried the different settings via the settings menu and the device itself. But that also did not work.
Problem solved.
It was device in automation with the issue
I had chosen the wrong entity. The switch only works via the device option.
Good to hear that you got the issues sorted out
