I wonder if this error is coming from home assistant not recognizing that the device has had its state changed. Stock FW antminers tend to take a long time to respond when the configuration endpoint is called, so when putting them into sleep mode it can take ~10 seconds to know if they accepted the command.

I’d like to add some clarification regarding the switch state issue.
Even though the service call to turn the switch on/off was executed successfully in Home Assistant, the application was not reflecting the updated state during the following cycles. Essentially, the entity states were not being refreshed at each cycle, but instead were being read from a cached state. Current states were only updated once the application was restarted.
For example:
Proposed solution:
With this approach, the entity state is now updated on every cycle, and the ON/OFF status of the switch is correctly reflected in the application. After applying this change, I no longer encounter errors when starting or stopping the miner via the switch.
That said, I’m not entirely sure whether this solution is the “right” one long-term — disabling caching might have unintended side effects in other parts of the codebase that rely on cached states for performance reasons. It fixes the immediate issue, but I’m not certain if it could potentially break other parts of the integration where caching is useful.
