At first glance I thought this would be a great gadget for me and it was very easy to set up.
I began to worry when it was showing the indoor CO2 levels in my home/office at 5000ppm. Tried it elsewhere in the house and it was showing very high readings and sent me into paranoid mode. Googling articles on high CO2 levels and blaming the house for every headache I've ever had.
In the end I spent £300 on a professional CO2 measuring device and discovered that my office levels are actually around 700ppm as is the rest of the house which is what I should expect living in the countryside.
Bottom line is I wasted £140 on the weather station and another £300 for piece of mind !!!
