I like the Davis Vantage Pro2 and I've never noticed any interference issues. It also has the best anemometer setup in my opinion since it's separate from the thermo-hygrometer, which is great for siting each of them properly. According to WXobservation, both the Pro2 and Davis' lower cost Vantage Vue transmit at just over 900mhz so you should be good around your home alarm. Unfortunately for you, it looks like the AcuRite 5-in-1 weather stations transmit at 433mhz. Hope this helps!
