hello mircho,
so the log is from the ioBroker adapter, which communicates via MQTT.
There are definitely reboots, I monitored that with a webcam. Using the log entries, I could always filter out the times and see on the display that Shelly is rebooting!
Another user has also reported this behaviour here: https://github.com/iobroker-commu…ment-1061716665
Cheers
