Rationing system

8.1.2023
Dear customers, due to the high demand, we are introducing a rationing system for our most ordered products from 9 January 2023. For more information about this method of purchase, see here. New registrations are temporarily suspended until January 16, 2023 to allow priority purchase for our long-term business partners.

Design change

22.8.2022
Dear customers, due to better availability, from 22/08/2022 we deliver all our controllers in slightly different installation boxes, which are functionally completely identical to the original ones, only they are slightly different in design - they do not have the bottom sharp edge. The size of the controller, i.e. the number of modules and other parameters, does not change. The absence of the bottom sharp edge also objectively facilitates the installation of the controller in the switchboard.

End of cooperation with Russia

25.2.2022
Today we ended our cooperation with Russia. No orders from this country are possible and no technical support will be provided. Also, Russian language will be removed from all our future software updates.

Price increase

1.2.2022
Dear customers, business partners,
Due to the ever-increasing prices of all input components and energies, we are also forced to increase the prices of our products and accessories that we offer. Price increase 1.2.2022
As part of the adjustment of our price lists, on the other hand, there was a slight reduction in software extensions.
You can find the new prices in our e-shop.
Thank you for your understanding.

Global semiconductor shortages

18.10.2021
Dear customers, due to these shortages we are not able to produce many of our products, especially wattrouters. The problem might affect even our other products, please refer here for further info and expected lead times.
