Not working since DST change?

[Plawasan]

Ahoj,

seems to me like the sensor stopped working properly this morning since the DST change ... or it might be a coincidence (PRE changed something?) however I'm not getting the same results now without any change to my config

- platform: predistribuce
  receiver_command_id: 605
