netatmo plus additional sensors,
This review is from: Additional Module for Netatmo Weather Station (Wireless Phone Accessory)
I bought the Netatmo a few months ago and apart from a couple of hiccups with the outdoor sensor losing contact with the main sensor it's worked fine. The sensors are a bit slow to respond too temperature changes so a rapid change in temperature will be missed but otherwise very good.
I've bought three additional sensors so I can see how the rest of the house is cooking when it's hot or freezing when it's cold.
Would be nice to be able to have an additional outdoor sensor as well but I'm getting too greedy.
