24.7.1 device unavailable

[TobiasPSP]

Up front, I don’t know if this is related to installing esphome 2024.7.1, at least this is what I did yesterday, and this is when I started to see this:

my SCD30 CO2 sensor continues to produce readings to HA in its designated 5min interval, however EspHome reports the device as „Offline“. It is shortly „online“ when I reboot HA, but after a while turns offline again.

Is there any new magic in esphome that possibly puts devices into new unresponsive power save modes? How could I diagnose this?

I am confused that the device shows up initially, and that it showed up before, so mDNS is definitely working.

many thanks!
