<template v-if="instrumentValue == 0 && facilityId != ''"> <SoilMositure :facilityNo="facilityNo" :facilityId="facilityId" :key="" ></SoilMositure> </template> <template v-else-if="instrumentValue == 1 && facilityId != ''"> <WeatherStation :facilityNo="facilityNo" :facilityId="facilityId" :stationName="facilityName" :key=""></WeatherStation> </template>
