Bought this to replace a (wired) weather station I'd had for many years. Found this easy to set up (be aware that you need to use 2xAA & 2AAA batteries, which are NOT provided). The system immediately linked up, the sensor 'talking' to the hub. However, I was a little concerned when it showed the temperature outside to be warmer than my external thermometer indicated. Then I realised it had warmed in my hand as I wandered about looking for the best location for it. After a little while it reached the same temperature as my thermometer.
It's default setting is to 'toggle' automatically between outdoor & indoor readings, but I found the flashing image a little irritating so reset it to reflect outdoor information only (I already have an indoor thermometer which keeps me informed). The hub is an attractive small(about the size of a 'post it') black case with a clear digital display, which sits on my window ledge. It'll sit freestanding, or flat on its back.
I've had it a few days now, and am very happy with it.

Fantastic value, quality product. Worked as soon as the batteries were fitted. Seems very accurate compared to more expensive thermometers I put it alongside. Inside and outside both read the same when next to each other for 5 minutes. And it has a humidity sensor in the indoor and the outdoor unit. Fantastic! Just what I wanted for my greenhouse! Totally recommend!
