Checking device status

At the moment scene can also be started with a trigger. Once this started there should be an option to check the status of another device and the depending on the status the action of the scene should be executed or not (or execute different actions/scene).
This will be a HUGE improvement and more than double eWeLink’s functionality (putting it on par with the best home automation software).
Example: If switch A turned on and switch B is on then switch on switch C. Thus if switch B is off when switch A is switched on switch C should not be switched on.

Try to set it up in the scene “IF” trigger by “all conditions are met”, like switch A and B are all on, then trun on C.

Thank you for suggestion.
In your example what will “start execution” of the scene - ie if switch A is turned on/off or if switch B is turned on/off?
