I have a Samsung Gear 2 and got it working with my non-Galaxy phone. (Gears are designed to only work with Galaxy phones initially) There are a bunch of people who successfully got the Gear 1 to work alongside Tasker cause the O/S in Gear 1 is Android. Gear 2 is different and uses a Tizen O/S so you cant put any Android apps on it. I think I may have figured out a workaround (maybe but need some assistance)f you were to click on that you will see this.. HEADSET SOUND REDIRECT

However if you go back to Tasker Plugins you will see in essential plugins a plugin called BLUETOOTH CONNECT.
Having
seen all this makes me optimistic that this can be done. Now I have a
S-Voice app on the phone but it doesnt work cause I am not using a
Galaxy. So lets just say this all needs to be done without using t he
cell S-VOICE app and only the S-VOICE on the Gear 2 watch. Can someone help me?
You can create a dummy notification on which you can intercept with tasker on creation. Through this you can pass information to tasker. Cancel the notification and nothing is noticed for the UI. Make the notification percistant and also the Gear 2 doesn't pick it up.From there you can do anything.
