Não sou perito em HA, mas se calhar a solução não é assim tão complicada, e creio que já vai ser mais facil chegares a uma solução.
O motor já tem já memorizado o tempo de descida e o tempo de subida ?
O codigo abaixo é usado no meu AC, e acho que com umas ligeiras adaptações e testes consegues chegar á solução para usares o RF no HA.
