Frostdale Nanogrid Light Switch temperature Sensor

I am building up a Z-wave network using Vera 3 and now have two Frostdale nanogrid light switches installed. The switches work fine. The temperature sensor I have configured to use the D_TemperatureSensor1.xml script and they display the temperature at commissioning, but Vera does not poll, so the displayed temperature stays at 20 deg C. How can I configure the devices to be polled say each minute?
