Very happy with it
We are using the H5100 to monitor our chicken coop and run. It has been really helpful knowing what the temperature is in the coop & run compared to the actual outside temp.
This system has been a great help keeping on top a three family house with a centralized heating system. The alert that system provide keeps me aware without being intrusive
While out of town for few days, the sensors made it easy to check the temperature in our home. After returning home, we use them to check humidity every day. Very easy to set up.
Awesome temperature sensors. They've been very accurate and reliable so far. I love the fact that I can check the temp when away from home. I'm using this for temperature sensitive work equipment that stays in the van. If the temp in the van goes too low very expensive damage will be the result. I can set a phone alert when the van reaches a specified low. Very awesome! Customer service is 5 start. I'm very impressed.
