저기 if (current time 부분 중심으로 보시면

파이어베이스에 저장된 오토라는값이 앱인벤터상에서 1로 바꿔주게되면 if 문으로 이제 오토가 1일시에 현재시간이 2407 보다 더 크면

( 원래 dht11이 측정한온도를 아두이노에서 그냥 t > settemperature.stringdata() 처럼 비교하려 했으나 컴파일 에러가 뜹니다 float t 어쩌고 하면서 뜨는데 

float인 t 는 비교가안되는건가 싶습니다 그래서 온습도를 파이어베이스에 저장된값을 다시 불러와서 이제 밑에 처럼 비교를 합니다)

파이어베이스 저장된 온습도값을 다시 가져와서

앱인벤터에서 보낸 설정 온도(settemperature)와 비교를해서 설정온도보다 측정한 온도가 크면 fan을 on 시키는 코드입니다 근데 돌리면 컴파일 에러는 안뜨지만 업로드시이 시리얼모니터에서 문자와 숫자 예를들어333ffff같은게 주루룩 뜨고 stack라는 글자가 밑에보이는것을 반복 와이파이가 다시잡혀요 무엇이 잘못된건가요?
