Got this for Christmas-temperature and humidity monitoring. Has 3 "tower" thermometers that send the readings back to the internet (via internet "bridge"device that comes with it and connects to your internet modem). Can set high and low temperature alerts (text and email) for each "tower". Can label each "tower" with your own meaningful wording (so you know the location). Will be nice to track the temps from anyplace -- whether home or not - via internet or cell phone app. Don't know if it will make me a better greenhouse gardener or not - but at least the plants won't fry or freeze. I have another unit that is not internet based that I got last year (with only one temp reading - this new one is great because I now have two GH joined (yet kept a bit separate with a curtain) -- and because I can monitor from anywhere via my cell phone.
