I'm actually a little giddy as I've finally got Alexa running my X10 without a computer doing the lifting (broadlink RM to CM15).
Now I want x10 events to trigger Alexa.
Example: my doorbell was just a button connected to a powerflash the ran X10WavPlayer. I'd like that to trigger a response on the echo devices. Any ideas?
I've been thinking about this a bit more (at least the door bell ) Amazon use to sell a small button that could be used for ordering and such they no longer sell these but Alexa still supports them. However if you can find one on Ebay you could replace your existing setup and use one with a routine.
I use to use
TriggerCMD for X10 notifications however this requires a yearly subscription if you send a command more the once per min. I ran it from my pi with HomeGenie.
I don't have this setup at my off grid place were I currently am so can't go into details as how exactly I had did it.
At my off grid place I have a ring flood light camera (given to me) set above my front door this notifies me through Alexa at both locations that there is activity by the door.
