@Blackpart Has this setup been working for some time or is it a new build? Either way that error usually indicates either a problem with the wiring to the sensor or a problem with the sensor itself.

@gloomyandy
Hello, the firmware was upgraded from 3.1.1 to 3.4.6, then this error was received. The wiring part was not touched -
@Blackpart almost certainly it is caused by a bad connection and it is coincidence that it started when you did a firmware upgrade.
BTW you have two M307 H1 commands in config.g. The first one should be moved to be after the M950 H1 command that creates the corresponding heater, and the second one removed.
