ᐅ Experiences with decentralized controlled residential ventilation systems?

Hello everyone!
Does anyone have experience with decentralized mechanical ventilation with heat recovery (e.g., Lunos or Aereco) that they can share?
I am considering whether the extra cost of a central mechanical ventilation system with heat recovery is worth it. The heat recovery probably won’t save more than €5000 in heating costs even over 20 years, but does a decentralized system work just as well? What about issues like the noise level of the fans or performance during strong winds? One disadvantage of older decentralized ventilation systems was the aesthetic impact on the facade due to too many ventilation openings, but nowadays there are more discreet options, such as ventilation through the roller shutter box.
I am familiar with the theoretical arguments for both systems (central vs. decentralized), but I’m genuinely interested in practical experiences from homeowners who have a decentralized mechanical ventilation system in operation.
Best regards,
Peter

I have been living in the new house with a mechanical ventilation system with heat recovery (MVHR) since September 2016. It is definitely possible to install a switch; most MVHR systems have a control unit. Mine has a control with an "off" button that turns off the fans and closes the damper.
That said, I have to mention that the damper in an MVHR system is not very effective in strong wind conditions outside. In winter, I had to make simple dampers myself using styrofoam with foam edges to cover the ventilation openings for a few windy days.
In summer, the system runs continuously, except when it is very hot outside.
