Hi everyone,
It seems like the main door is down. I tried my card and it’s not responding. As I see there is no led light flashing either. Is anybody coming today to the lab? Ideally with a key? Cheers! Tusk
I will stop by. n.

Hi,

In short, Brmdoor should work again.
Postmortem:
There was a faulty old power supply where capacitor exploded.
In the meantime, battery that was as backup drained over days to a level where it seemed unrecoverable.
After replacing power supply 1st time, it worked for a while, until it wasn't able to power the system. Instead of expected 12V input the levels fluctuated periodically around 4.4-6.8V so Raspberry behind stepdown was in constant bootloop.
This part was "funny" since Raspi started booting, you could repair/fsck boot system, but it never got anywhere.
We replaced the power supply again, disconnecting/bypassing the battery, it seems to be working now and for the love of god I hope the power supply won't fail anytime soon.
