Many SmartHome devices have there own skills and these skills can be expanded on using Alexa routines.
Not sure if Google has something similar to routines (I just don't use mine enough)
However I found a couple that can expand your HA setups potential.
1: TRIGGERcmd Smarthome, this is available for both Alexa and google and allows you to control many none smart devices even X10 devices.
2: Voice Monkey, this appears to only be available for Alexa
it allows custom Alexa voice responses from button presses
Both these do require some time to setup but both would work with AHP(x10), other software or other Skills.
Both are free, however there are use # limitations for both.
For
Voice Monkey you can create as many virtual triggers or buttons as you need (up to the Amazon limit of 300) for FREE.
For
TRIGGERcmd Smarthome you can only make 1 Alexa/Google request per min. If you need more then that you have to subscribe.
It will send you a please subscribe email each time you try to make more then one request per min. A subscription is $19.95 per year
I suggest you play with it for a while before you subscribe. The developer has also stated he'll look into doing something similar to what Voice monkey does for the Smarthome skill in the future.
There are lots others on here that use Alexa & or Google much more then me so they may have their own skill recommendations
