The closest way I know to do it today is to
TRIGGEr - use my app to “trigger” the question you want Alexa to ask you.
CONDITION - Use the Alexa app to create a unique but real answer (with Alexa keyword)
ACTION -Use the homey integration to action a flow
So when it’s 35c on a Tuesday and the blinds are open. Alexa app voice command “Hey jamie do you want me to cool things down?
Alexa routine , “yes, Alexa cool things down”
Alexa routine triggers homey flow which closes blinds , closes window, turns on fan, sets aircon etc etc. on success then Alexa says “no problem, all done”

That’s your best bet because I have no need for this so therefore no interest in coding it.
