Found the solution with Alexa what you do is
1- using Harmony app, edit favorite, select tv (kitchen lets say) assign all the favorite channels and save/sync....
2- Go to alexa app, disable Harmony skills and enable it back, log in and goto favorite screens.... edit your channels with room specific id like changing NBC to NBC KITCHEN... do this for all the channels...
3- As always after linking the Harmony back up to Alexa, run DISCOVER DEVICES, this will add all the favorite to ALEXA and saved as device specific.
dont worry about the link failling because took you too long editing favorites in Alexa. This is because the delay was too long, reenable the skills hit arrow till the link screen, and link it again, the changes are always saved..
Redo all 3 steps for each tvs... Et VOILA... IT WORKS!
Simply call up Alexa, Turn on NBC kitchen... to get NBC in the kitchen...
Alexa, turn on Cable News Bedroom... to get CNN in bedroom....
Alexa, turn on PBS in livingroom... to get PBS living room...
To control volume or other TV functions, use Alexa, ask Harmony to mute bedroom cable tv (name I gave to the activity)... et AGAIN VOILA....
Only problems left are;
1- Power issues, if I turn OFF on room it turns off all 3! Kids luv this one! Arg!
I know about the power sequencing config in the device config of Harmony app, this aint it... its done correctly, its something else...
2- remote assignment, well this one is funny (for the kids, ARG,!!), after an Alexa command is sent to a TV the remote is now assigned to that device... ARG!!!!!!!!!!!!
You have to reselect the device on the remote or else, you are now controlling the last device called out on ANY of your Alexa... via that remote... this one is a pain...
More to come, This is grand and IT WORKS have fun... ok with a couple of bugs...
This is grand and IT WORKS have fun...
Update, Harmony supported indicated that left over bugs were because Harmony skill is design for single tv! Arg!
