Alecto Weather Station - WS-5500

Review of a weather station with many sensors.

We haven't seen much weather stations on our blog yet. So it's high time to provide one with a review. We immediately called in the mother of all weather stations: the Alecto Weather Station WS-5500. We are going to install it and look at the possibilities and of course link it to some different Smart Home systems.

Alecto is a manufacturer that has been making "weather related" products for many years. This varies from a simple thermometer to very extensive weather stations. These mainly worked via the 433Mhz protocol and could be linked to, for example, a Home Wizard system. Nowadays you see more WiFi weather stations appearing, including this one from Alecto. This WiFi connection is only used for internal communication. The 866Mhz frequency is used for communication to the sensors. You see this more in weather related products.

8 sensors

This weather station is equipped with 8 different sensors:

- Temperature (indoor and outdoor)
- Humidity (indoor and outdoor)
- Air pressure
- Wind speed and wind direction
- Precipitation
- UV and solar radiation

A 7" color screen is included with the Alecto. There you can read different values. You can also view a calculation of the wind chill, heat index and dew point. In addition, you can view the lowest and highest temperatures and read the forecasts.

There is also space for the time and date. And there is an alarm clock with snooze function. It is powered by the included adapter and you can also place 3x AAA batteries in it as a backup (should the power fail).

Green powerrrr

This weather station has a built-in solar cell that supplies it with power. This is very nice because you often hang a weather station in a place that is difficult to reach. This way you don't need it anymore.

This weather station can be linked to Weather Underground. This is a worldwide weather service with more stations connected (>200,000). Because this is used, it is possible to connect this weather station to a Smart Home system. You can also use the Weather Underground APP to request the values ​​of the station and view (and save) statistics. More on this later.
