Today, WeatherFlow Tempest got enough solar radiation and it woke up! Battery voltage has so far increased from 2.33 V to 2.37 V. This means we are getting Wind, Solar Radiation and UV Index. Having Wind value, Feels Like can be calculated, too. Measuring Gusts would require even better battery status–with this status Wind is...

Image below shows well current temperature compared to January 2020. Getting cold!

Station Master created an image clarifying the current Weather Station Nagu hardware and software setup. WeatherFlow Tempest should provide all weather data, but since it went offline due to lack of solar power, some data is collected using RuuviTag (temperature, relative humidity pressure) and old Davis equipment (rain). Home Assistant reading RuuviTag originally served our...

Rain measurement uses old Davis rain gauge, so it was possible to publish online, too. Wind, Solar Radiation, UV and Feels Like (dependent on wind measurement) will not be available until Tempest is back online.

Station Master was able to restore Temperature, Humidity and Barometer updates. These measurements are based on Ruuvi beacon.

Due to low power status of WeatherFlow Tempest, WS Nagu is currently offline. Station Master is trying to figure out how to obtain at least some of the measurements, but this may take some time.

Due to low battery status, Tempest’s wind sampling interval is only once every five minutes and gusts are not reported. This is the main reason wind is not reported as strong it really is. Waiting for manufacturer’s solution to the lack-of-solar-power-on-high-latitudes issue.

We got first snow cover on Xmas Day. Station Master turned on rain collector heater. This must be one of the latest winter days of station’s history to do that.

Due to low power state, Tempest has set some sensors completely offline and with the rest of the sensors, sampling happens with 5 minutes interval only. This is why Tempest is currently not able to register rain and wind gusting. Station Master hooked old Vantage Pro rain bucked back online and restored rain data collected...

Currently WS Nagu is not showing rain due to WeatherFlow Tempest low power status. Station Master is working on to connect old Davis rain bucket online to get rain measured in these situations.
