I would like to have 2 temp sensors positioned on 2 different places and would like to have smart heating / cooling. Scene should have a logic like this:  
If SNZB1 Temp \<= 20 switch MINI ON  
If SNZB1 Temp \>= 23 switch MINI OFF  
If SNZB2 Temp \<= 20 switch MINI ON  
If SNZB2 Temp \>= 23 switch MINI OFF

BUT my problem is if SNZB1 says switch off and SNZB2 is on switch on, I would like MINI to stay on ON.

Is this possible using smart scene or any other way? Thanks

In the app, you can create a scene based on multiple conditions.

In your case, you need 2 scenes:

- If ‘any condition is met’ with ‘SNZB1 Temp \<= 20’ and ‘SNZB2 Temp \<= 20’, then ‘switch MINI ON’
- If ‘all condition is met’ with ‘SNZB1 Temp \>= 23’ and ‘SNZB2 Temp \>= 23’, then ‘switch MINI OFF’

That should switch your Mini on when either of the temperatures are lower than 20 and switch it off only when both temperatures are higher than 23
