Weather Station Nagu currently relies on three different set of sensors: Weatherflow Tempest, Davis Vantage Pro and Ruuvitag. A while ago, Tempest’s humidity and rain sensors stopped working, but luckily this did not cause any issues, because those measurements shown on WS page are not from Tempest.
However, faulty Tempest will be replaced with a new one. It has already been shipped from Florida, USA. Weatherflow’s customer care is excellent.
