I have 13 shelly relays and they have (or so I thought) been 100% rock solid. They are connected with either (where ###.###.###.### is the IP address of my Home Assistant Supervised Instance (which has a native integration with Shelly)):
CoIoT: ###.###.###.###:5683
or
Outbound Websockets Default TLS: ws://###.###.###.###:8123/api/shelly/ws
They are always available and react very quickly to any automations, always have a strong wifi signal, etc. To try to minimize heat on the units to extend their lifetime they have been set to “ECO Mode” as well and that has made really zero difference.
So here is my question. One of them is a Dimmer 2, and everything works perfectly, however at least once every couple of weeks the light will suddenly go off and then back on within about 1 second. I thought I coudn’t find anything in the logs, but I did discover in the SYSLOG right at the same time:

Aug 15 13:27:46 kruse-pi homeassistant[688]: #033[31m2023-08-15 13:27:46.296 ERROR (MainThread) [homeassistant.components.shelly] Error fetching Den Shelly Dimmer 2 data: Error fetching data: DeviceConnectionError()#033[0m
I would rather not turn off ECO mode as with some models of the Shelly relays that will make them up to 10 degrees F warmer.
Has anyone encountered this issue with a dimmer?
