I’ve built the air quality monitor according to these instructions: https://learn.pimoroni.com/tutorial/sandyj/enviro-plus-and-luftdaten-air-quality-station
It works quite well, when I start it from the terminal and also after a reboot. But when I try a restart with power off/on, there is only a bunch of colored pixel shown on the enviro+ display and apparently no data transmission to the luftdaten-server.
What can be wrong? I would be very grateful for any helpful hint.
