In general

  Our goal was to create a station which can be used almost everywhere. We started to develop Holfuy in the beginning of 2011. Holfuy uses Solar power and Cellular/Mobile or WIFI communication so it can send data from every site where cellular network and sunlight are available. Thanks to the technical innovations in the last few years we could integrate the whole system in one small box. We made a user friendly WEB based system where our users can check the station's data from desktop and mobile devices.

Data storage and visualization

  A standard station automatically sends it's measurements to the Holfuy cloud. The Holfuy servers store every single data packet from the stations. Visitors get access to the measured weather data for the last 5 days. The station administrators can analyze or export older archive measurements after logging in. You can check the actual and archive weather data with every web browser (mobile also), or with our mobile applications (iOS and Android).

  For other websites we offer different modules/widgets, more info here. As an extra service we can redirect every single data packet or the averages to your server also. We support many export formats (e.g. JSON, XML, CSV). Please contact us for more details.

Weather sensors

  Holfuy stations can support many different environmental sensors, which could be optionally connected to the stations. We have low power solutions for the following sensors:

 + Wind speed, gust and direction
 + Air temperature
 + Humidity
 + Water temperature
 + Air pressure
 + Tipping bucket rain gauge
 + Wetbulb temperature
 + Soil temperature, moisture
 + Leaf wetness
 + Solar radiation (W/m^2)
 + Light intensity

If your application requires other, special sensors, please contact us.

Events and missions

  We can support your event with real time weather data by up to 12 Holfuy stations from 1day to 1 months period. We can help with the installation, we offer special data visualization modules, map views, or we can just send every data to your server real time.
For missions: Since our stations can also be installed at harsh locations (high altitude, desert, nordic climate zones, etc.) we could help to turn even your extreme ideas to reality. Please contact us for quotes and details.

The Holfuy Team

  We are a small team of creative, flexible engineers and developers with very strong focus on our customers' needs. When we are not working on Holfuy we love to spend our time outdoors (hiking, paragliding, kitesurfing).

  We carefully test every single station before shipping. But we're only human, and occasionally a problem might slip through. The statutory-legal guarantee covers the productions defects of the Holfuy products for a period of one (1) year (24 months for customers in the EU for the station itself, 12 months for the sensors) from the original shipping day (when we sent the station for you). During the warranty period, we will repair/replace the damaged part of the station free of charge. Please note that buyer pays for the return shipping to Hungary. This warranty doesn't cover any damage due lightning, shock accident, physical damages, natural wear.
Please contact us first if an error occurred. We will help to find the cause of the problem first.
