ᐅ Roller shutters close unexpectedly

Hello everyone,

My family and I are slowly going crazy and hope someone here can give us some advice.

Background:
We have electric roller shutters throughout the house. The switches for these are from the company Kaiser Nienhaus. At each window, we have the Tastor Comodo, and in the hallway, as central control, the Tastor Konsum (without additional sensors).

After about 4 years, we had the problem that the shutters at the large windows on the ground floor (plastic) started to "fail" one after another. They would close and then could no longer be raised. Since the installer did not respond, I had to turn to another local technician. He convincingly told me that plastic was not a good idea for windows of that size and recommended replacing the large windows with aluminum versions. We went ahead with this replacement.

Now — just a few days after the replacement — some of the shutters move down automatically. Usually one or two at a time, often the same ones. It is clearly noticeable that this happens about 90% of the time in wet weather — so I suspect a connection with the installation of the aluminum shutters. To be safe, I replaced the central Tastor Konsum with a new one — unfortunately, no improvement. The installer strongly denies having anything to do with it and points to the electrician.

Before I bring in an expert to inspect the house — do you have any ideas? Besides the switches mentioned above, does there have to be any other control system in the house? Unfortunately, the electrical company involved in the build is no longer in business.

It’s really driving me crazy... Thank you very much for any tips!

Best regards,
Robert

Do any of your neighbors also have radio-controlled blinds? Now I’m going out on a limb here: aluminum roller shutters can amplify the signal due to reflections, and this “smog” might trigger your actuator. I’ve experienced something similar myself.
