Windancer GPS Modbus: weather data straight into your Modbus system

News of 05 November 2026

Weather data for your Modbus system

Whether you want to control external venetian blinds in storms, roof windows in rain or slats that follow the sun: weather-dependent building automation relies on accurate outdoor readings.

That is exactly what our new Windancer GPS Modbus weather station delivers, from brightness for the east, south and west façades to wind, precipitation and temperature. It also calculates the sun position and passes azimuth and elevation to the controller as ready-to-use values.

For your project, this means one compact device instead of several individual sensors, addressing and interface parameter settings via DIP switches, and a single query for all readings. Wiring and programming stay lean as a result, sun tracking included. The cup anemometer and heated precipitation sensor ensure that storm and rain protection are triggered reliably.

For projects that only need the weather data, Windancer Modbus is available as a basic version. Both versions are available now in the Elsner Online Shop.

Legal guarantee

Harmonised EU legal guarantee notice

Minimum two-year legal guarantee protection for goods sold in the European Union.

Consumers can claim their rights under the legal guarantee of conformity, for example if goods:

  • do not match the description;
  • do not function as intended.

Sellers are liable for any lack of conformity which existed when the goods were delivered, and which becomes apparent within the legal guarantee period. Sellers in such a situation are required to offer:

  • free repair or free replacement;
  • in some cases, a price reduction or full reimbursement.

Some countries have a longer legal guarantee period. For second-hand goods, a shorter period may apply, but not less than one year.

What to do if you receive non-conforming goods:

  1. Contact the seller as soon as possible to report the issue;
  2. Provide proof of purchase, such as a receipt, invoice, or bank statement.

Sellers and producers may also offer commercial guarantees, which apply independently from the legal guarantee. For example, you may see this GARAN label representing a commercial guarantee of durability offered by the producer at no additional cost and covering the entire good.
