Have about 20 Insteon's (switches, thermostats, relays, water sensors), about 15 Zwaves (mostly switches, some temp sensors), and probably 20 simple active programs.
I will do some searching for the Zwave 500 series and whatever "Polisy" is. Up till this point it's been super simple to add devices and programs... but maybe after a solid 9 years of use it is time for an upgrade!
