For me too. I setup a couple of wireless 433Mhz temperature/humidity sensors in my flat (one on the balcony, one on the sauna).

Turns out the balcony sensor was just that little bit too far away to be regularly detected. However I noticed that I could get temperature readings from the car-tyres parked in the carpark to the side of my flat.

So I switched to using those instead for my "outdoor" temperature. Works a little better than my balcony would have done, as that is glazed and warmer than the actual outdoor temperature.
