No, I do not think so.
The status of Shelly Cloud works absolutely without any problems.
So BLU Device to Gateway Shelly to Cloud is error free.
BLU Device to Gateway Shelly to Openhab does not work permanently.
I’m currently testing how long it works, or how long the script on the Gateway Shelly is on play.
Maybe the ECO mode of the Gateway Shellie plays a role?
