Putting the OptiSmart to creative use

SW:
CurrentCost plugin (http://code.mios.com/trac/mios_currentcost-envir) and
luup.variable_watch( 'update_gamma_dose_rate', 'urn:micasaverde-com:serviceId:EnergyMetering1', 'Pulse', 259 )
function update_gamma_dose_rate( lul_device, lul_service, lul_variable, lul_value_old, lul_value_new )
if gdr_startup_time == nil
then
