What our customers say about us


Michael B.

The ease of configuration and the list of compatible products have been very well received by us.


Axel L.

The possibility to display graphics and thus visualise the energy flows is great! Thank you for this new possibility!


Markus K.

Thanks again for the great service. I am thrilled.


Harald K.

I am very pleased with the new version 1.16.0 of the firmware. PRAISE!



It's really great how you expand the functions and respond to customer feedback... I know that in the end you can't please everyone... But (no matter how the "PV charging logic" turns out in the end) that's the reason why the second wallbox (for the parking space in front of the house) will also be a cfos and I recommend the wallbox to anyone who asks (or doesn't ask 😉).


Andreas B.

I would like to formally thank you and also the company cFos for such customer-friendly action and the smooth replacement of the meters.
