Any way to control a DreamColor TV from a Harmony Hub?

I got a DreamColor TV (H6104) for each one of my TVs, really like them but I can't figure out a way to control them using my Harmony remotes which do control everything else connected to the TVs really well... Kind of a pain to pull the cellphone and open the app to turn them on and off independently...

Any known workaround for this?
