[Bug] Plugin didn't switch off devices anymore

[JayJay-Master]

Describe the bug
After some time the plugin didn't switch off some devices (Shelly 1 and Shelly Dimmer 2). With a restart of the child bridge the plugin works as it should, but after some time (1-2 days), it is only able to switch on a device, but not to switch off. Device is shown as switched off, but it's still on.
In Shelly App the device status is shown correctly.
