Sync Alexa Command With Custom Harmony Card

A while back I set up the custom harmony card and it works great for the most part. We use the Fire TV Recast and find it easier to say “Alexa Watch channel 8” or using the Fire TV remote to turn the TV on. Is there a way for the states on my Lovelace card to sync with my harmony card? I’d like to make a channel change via lovelace after it is turned on with voice or the alexa remote.
