1-wire stops working after period of time
I have three DS18B20 temperature sensors connected together, and configured. This usually works well, and all three temperatures are visible in the configuration page and also via the API.
However, randomly after a period of time it stops receiving any temperatures (See screenshot below).
This can only be resolved by a power cycle of the C6 device (a soft reset / reboot doesn't fix it). There are no relevant errors in the device logs.
Any idea what might be occurring, or how to debug further please?

please check again with the new release as the 1wire component was updated which e.g. activates a pullup
I ran a long-term test with 2 sensors and after almost a week these are still sent to MQTT regularly
