It works, monitors temperature and humidity immediately and has normally open contacts for additional sensors. I bought a water bug sensor from Amazon and it works great. I don't think the temperature is really accurate, but I only use it to alert myself if the air conditioning in the room is going out, so it's not necessary. If you want something really accurate in temperature I would choose a different item.
