I also got Alexa working through IFTTT using Blynk since we already set it up for OG.
You can incorporate filter code in an IFTTT applet if you become a Maker (free):

Unfortunately, that is beyond me. Perhaps doing the status check through a custom Alexa skill would be possible?
Edit: Apparently Alexa can only trigger IFTTT applets. There is no functionality to make Alexa do anything. An Alexa skill would be the only way to get her to respond to an inquiry.
