It's closed, but the planned events are on-going till 31st of December 2026. If there is an event in the list that suits you're agenda, you can still see the museum.
(Do note I try to go to Berlin once or twice a year to visit friends - so the news of the (more impending than I realized!) closure of the Hoyerswerda museum simply made me get this fall's visit booked...)
I haven't been to the Deutsches Technikmuseum since October 2024, so I'll probably make another visit there.
Also, this museum is closer to Dresden than to Berlin...
