A commercial $75 solution is the HSM100 - Z-Wave Multi-Sensor which
incorporates motion, illumination (light), and temperature sensors in one
battery-operated, wireless module.

As I understand it, one has to run Z-wave on HomeSeer to make the light and
temperature work.

One can hope that SmartHome comes out with an upgrade to their 2420M INSTEON
wireless motion sensor to provide temperature, humidity and light sensing,.
