In less than a year, it started not receiving signals from the external sensor. I changed batteries in both the main unit and the sensor, I reset it, I went through the pairing process again. Nothing. At some point, after 2 weeks, it started connecting again. But after a few days, the same thing happened again. It's not a distance issue, I have placed the sensor next to it, on the table for days and it doesn't connect. It didn't prove to be reliable.

Regarding the temperature, it shows quite accurate. Specifically, for the external temperature, I compare it with the car thermometer and usually there is a small deviation of half a degree. I don't have anything to compare the hygrometer with, so I can't say anything. The weather forecast is random, but since it's not something I need, I didn't factor it into the rating.
