I’ve seen lots of complaints about how long the Harmony switches in ST take to update when using the physical remote to turn stuff on or off. Just found a really simple way to get instant state updates. Go back and add all of the ST switches to your Harmony hub as Home Control devices, then turn each corresponding one on when your activity starts and back off when it ends.
Bam, instant Harmony status updates.
Step by step below. This starts with the assumption that you’ve already added your Harmony hub(s) to SmartThings.
Open the Harmony app on your phone (as far as I’m aware, the phone app is the only way to add/edit Home Control devices)
If you have multiple hubs, connect to your target hub. These steps have to be repeated for each hub.
Add your SmartThings switches to Harmony as Home Control devices.
a. From the main screen in the app, tap the hamburger menu in the top left corner, then go to Harmony Setup -> Add/Edit Devices & Activities -> Devices
b. If you have not previously connected your SmartThings account to your Harmony hub (i.e. SmartThings doesn’t show as a Device), tap Add Device -> Home Control -> SmartThings -> Sign In
c. If you have previously connected your SmartThings account to your Harmony hub(i.e. SmartThings shows as a Device), tap on SmartThings -> Re-login
d. When prompted, log in to IDE, select your ST Hub from the drop-down, select the SmartThings switches that are associated to all of your Harmony activities, then tap Authorize at the bottom.
You should be taken back to the Harmony app, but if not, there’s a link on the screen that you can tap to re-open it. The Harmony app will spin for awhile, and if you’re lucky, will finish. If you’re like me, it never stops and I have to Force Stop the app, then relaunch and go back into Add/Edit Devices & Activities again. When looking at your Devices, you should see SmartThings listed, and if you tap on it again, you should get a list of Lights and Plugs. All of the SmartThings switches will be listed under Plugs. If they aren’t there, try tapping on Refresh.
Once all of the switches are showing, go back and edit your Activities. Harmony Setup -> Add/Edit Devices & Activities -> Activities.
a. Tap on your first activity, then go to Edit Start Sequence
b. Scroll to the bottom and tap on Edit Home Controls
c. Select the correct SmartThings switch for the activity, tap the next arrow at the top right
d. Check the box for the switch, select On (note - this will turn on the activity), tap next arrow, next arrow again
e. Tap on Edit End Sequence, Edit Home Controls
f. The correct ST switch should already be checked, tap next arrow. Check the box for the switch, set device state to Off (note - this will turn off the activity), tap next, next
g. Repeat step 5 for each of your activities
Example…this is the startup sequence for the Fire TV activity on my Living Room hub. I tied the ST Living Room Fire TV switch from ST back to the startup sequence in the Harmony hub.
