Anyone know of a smart app to open switch on a time AND date

anyone know of a smart app to open switch on a time AND date.

got smartvent… need to close on dec 1st and open on apr. 1st… got it where office is too hot in winter and keep forgetting to close vent to stop heat from going in, but need ac in summer. dont want it based on temp, so dont recomment that.

webCoRE can use date logic in its pistons.


That should not be difficult to write a smartapp for that.
Pickup any smartapp that drives a swtch and use runOnce per

Should be really few lines of code.

Yep already did thanks
