Many thanks for your valuable comments!

If I read [this former comment from you](https://community.openhab.org/t/oh2-checking-state-after-rule-received-command/28373/2) and [this part of the documentation](https://www.openhab.org/docs/configuration/rules-dsl.html#event-based-triggers), then my understanding is:

- sendCommand(x) sends a command and the according binding acts on this by sending it to the device
- Here I don’t have a binding, but just a pure item. Therefore the autoupdate gets for sure involved and updates the item’s state.

But one question:  
Can I expect in a rule fired by “received **update** ” in this scenario, that the item’s state is for sure set to the value which I sent via sendCommand?  
Or is the same true, which is documented in the link above for rules fired by “received **command** ”: Means it may happen, that the rule is triggered **before** the item’s state is updated!
