I’ve done this exact thing by creating a virtual momentary button tile called “Den Fan Low” then created a rule using Rule Machine that triggers based on this momentary button tile.
Rule:
Select Trigger Events:
Den Fan Low On
Select Conditions:
Dimmer level of Den Fan != 32
Den Fan off
Define Rule:
Dimmer level of Den Fan != 32
OR
Den Fan off
Select Actions for True:
Capture: Den Fan
Dim: Den Fan: 32
Select Action for False:
Restore: Den Fan
The with Alexa all I have to say is “Alexa, turn on Den Fan Low”.
Works great but does require 3 virtual momentary button tiles and Rule Machine rules for each fan. In my house that is 5 fans, so I would love to hear if anyone has a better solution.
