Which App is best to use with IOS and Android.

[VaughnVenter]

Is there another way of configuring the board as we need to do more complex coding than what we can do in the IFTTT that will still work with the Tuya app.
Is it posible to create a internal variable that can be used in the Tuya app to set setpoint. eg.
If Temp >= Setpoint then R1 on
Setpoint must be adjustable from the Tuya app.
