Overview
Non-mechanical sensors measure wind speed, precipitation, lightning, UV index and temperature in one solar powered unit, and the readings go to an app or Alexa.
Non-mechanical sensing, solar power and an app make it a low-upkeep outdoor station, and lightning and UV are covered. The limitation is that there is no screen on the unit, so every reading depends on the app or Alexa.
Who it's for
A homeowner comfortable with an app who wants wind, rain, lightning and UV in one unit will use it. Forecasts come from machine learning. Anyone who prefers a standalone screen should look elsewhere.
Pros and cons
- Lightning and UV sensing
- App and Alexa control
- Machine learning forecasts
- No display on the unit
- App needed for readings
- Connectivity rows unclear
Performance notes
The sensors read wind, precipitation, lightning, UV and temperature, then the unit sends data by radio to the connected app. Solar power charges the battery, so placement in open sun and open air matters. Forecasts are generated by machine learning from those readings.
