Bests & Worsts Reviews from Amazon

First of all, the product description is misleading. It purports to be a temperature and humidity monitor, that you can use to monitor the temperature in your home via the free app for your smartphone. There are few details in this product's description, but after you get it, you find that in order for it to work with the app OUTSIDE your home, you need to purchase a hub. I'm not sure what value the app would have to monitor the temp INSIDE your home, as you could just look at any thermometer and see what the temp is. So you get the hub (another $50) and the documentation for setting up the hub and the meter are almost useless. And the app DOES NOT act like the documentation says it does. Once you set up the hub, getting the meter to work with it is not easy, nor intuitive. On the first time through setup, I thought it was done (although it also just looked like it stopped), but there was no meter defined to the app. Trying setup again, I noticed a "checkmark" at the top of the screen, that needed to be pressed. It is in a place I would not have looked for... I was expecting a button that says "Done" or "OK", like the previous screens had ("Continue"). There are all kinds of things that are confusing, like what does "inverse" mean, as it applies to the settings? It's below "Temperature" and above a slider for the temperature range. There is a setting for Celcius/Fahrenheit in "Preferences", but that does not affect the meter... just the display of data on the app. I discovered that the button on the back of the meter adjusted from "C" to "F", but that's not anywhere in the documentation. Then there's the data itself. After playing with it a while, getting it to work (no, it's not just a few minutes, unless you designed this thing), I wanted to clear the temperature and humidity data. There's button on the "Meter History" page, labeled "Clear Data", but it's not a functioning button... I have no idea how to clear the data out. Maybe it rolls off after the memory is full?? But, then, maybe the device just stops recording when the memory is full... I don't know and don't see how one finds out... until the memory fills up. Oh, yeah... how much memory is in this little device? It's supposed to poll the temp and humidity every 4 seconds, but I can't imagine it takes much memory to story that data. There's a neat little graph on that page, with dates and times, but it doesn't have a scale on the graph, so you have to look at the avg, max, and Min to see where the temp has been. I looked at the "Scenes" functionality. I expected it to give me an option to have an alert sent to my phone if the temp went out of range. Interestingly enough, the temperature conditions SHOW "higher than" and "lower than" and a temperature, BUT I can't get it to switch to "lower than". And the "actions" block has nothing I can choose. I suspect that's because I only have the hub and this meter. Maybe, if I had more devices, it would allow me to do something with one of them, as a result of the temperature going "higher than". Overall, I'm unimpressed, regardless of the hype the manufacturer puts out about how this is the best home automation product available, etc. I'm going to use it for a couple weeks and see if my opinion changes. Otherwise, this is looking like an Amazon return for me.
