Business ProfileforEmerson

I purchased an Emerson ***** **** *********  four years ago. I noticed that it wouldn't always be connected to the internet... I would just reconnect it when I was around, yes it was inconvenient , but I didn't think much of it. We travel quite a bit thus the reason why I wanted to ensure our home had heat as we live in a colder climate and did not want my pipes to freeze. Michigan just had another ice storm once the power and internet was restored I wanted to check on my heat. No connection... all my other WiFi devices had reconnected except for this thermostat. Our home is a smart home so we talking many many wifi devices that are running and reconnect without issue, **** my refrigerator even connects to my WiFi. I called the ***** tech support (talked with ****) find out if there was an update or something on my end I could do to deal with this on going connection issue. The tech told me I had to reconnect it by manually reconnecting the WiFi connection. I told him that I was over 1200 miles away from the device and he told me that is the only was to reestablish the connection. I asked what is the purpose of having a connected WiFi thermostat then and he replied that is just how they work. Well, I several friends and family that also have WiFi thermostats and don't have these reoccurring issues. This Tech then on to tell me that my router is detecting my device as intruder and is probably blocking the reconnection. I have ******* and ALL other devices reconnect so I don't believe that it the problem.
