Request the status of a Home Assistant entity that is not defined in the MySensors integration?

[Gibber]

I am trying to use a battery powered node to control a window blind. The sleep function does not cooperate well with a control entity due to the sleep delay interfering with the acknowledgement timing.
I saw in another post that there is no "optimistic" mode available with the MySensor integration.

Does anyone know if it is possible for a node to request the status of home assistant entity that is not defined as part of the MySensor integration?

With some logic in home assistant like in an automation or node red, this is possible. Use a helper function to set the state, and request that status from the node

Thanks for the response. Can you be more specific about how to request the status from the node?
My understanding is the request format is:
request (Child_ID, VariableType);
But if the Home Assistant entity that I want to request the status of is not a MySensors entity it will not have a Child_ID. So how do I format the request statement?
