I’ve got the lifx bulb set up on one of the home control buttons on the harmony remote now, and set up a smartthings routine to turn on the smart plug when the light is on, and off when it’s off.
I was hoping that there’d be more control options within harmony for the bulb other than just on and off so that I could assign the other controls to my other smart plugs but it doesn’t look like this is possible.
Is anyone aware of any way of doing this?
I’ve realised that another solution to this is to get a Philips hue bridge and compatible smart plugs.
For anybody having problems with their Harmony Hub connecting to SmartThings (ie it used to work but no longer does) then I can confirm that this worked perfectly and my Harmony Hub is now controlling things in SmartThings again (I use TP-Link extension leads which I turn on and off but this should work for any device). Thank you so much for this.
What I did (as per original post)
Works like a dream 
The driver continues to be the integration that stops me from losing my temper and junking anything Harmony for good 
Thank you so very much for the updates you have made @lmullineux
I do have a question on the feasibility of somehow getting the home control buttons on the remotes into the mix with this integration. I get that with the driver we can now send commands from smart things via the hub and that activity states can be used as triggers in smartthings
My question is if it would be possible for the home control buttons on the remote could somehow trigger something in smart things? The biggest impact on the broken native integration is that the lights and plugs that the remote could previously control is no longer functioning. Any realistic way that the signals sent by harmony to smart things could be reserected?
This has been covered several times. Unfortunately this would require Harmony/Logitech to do something at their end. It does not look like that is going to happen but anything is possible.
Thanks so much for this!
There is one thing that I used to do that I can’t seem to get working. My TV will power off after a certain period of inactivity. Using WecCore, I was able to sync the state of the Harmony activity by setting the activity to off rather than turning it off, essentially just updating the state without actually switching it off. (I know the TV is off by reading its power draw.) Then, Harmony would know it’s off and if I turn it an activity on, the TV would come back on rather than stay off, with Harmony thinking it’s already on.
I guess my question is, is the bridge able to set the state rather than flip the state or, in other words, can it tell Harmony that it is off without actually turning it off?
Thanks!
Looking at this from the root cause aspect, that sounds like a power save setting on your TV. Can you not change that so that it simply doesn’t turn itself off?
Yes, but I actually want the TV to turn off if it’s sitting idle…
Hi sorry for the slow reply, I’m currently on holiday and staying away from the computer.
The short answer is, No - there is no way that I’m aware for an activity to stop without it actually executing it’s power off routine inside harmony. (But I’ll look into this properly when I’m back)
If you have power draw, could you have a routine in harmony to check power draw after the activity is started, if it’s below a threshold send a harmony device command to turn on the TV?
This is a strange one.
One of my hubs have suddenly started doing things on its own.
So if I’m watching something on my nvidia shield, it’ll suddenly go back to the Home Screen, and the volume goes down, like it’s some sort of automation. I don’t have any sort of automation.
Has anyone else experienced this at all?
I have not experienced anything similar. What makes you think it’s your ST hub that is causing it?
If I was in this situation, I would systematically remove items from the setup until the problem stops.
Disable the st integration (just temporarily change the IP on settings)
Disable harmony itself, just power it off
Disable Bluetooth devices connected to the shield, 1 by 1
Until the problem stops, when it stops you’ve probably found the location
Anyone’s just stop working all of a sudden?
No problems here. What exactly stopped working? Remember that Logitech/Harmony shutoff the direct integration some time ago (IIRC around June) so directly controlling ST via the device control buttons at the bottom of the Elite no longer works although their are a few work arounds using other devices/integrations (scroll back thru the discussion here for info).
I have about 8 hubs working great. I’d say in the last week all of a sudden any command in SmartThings doesn’t respond. Had it linked to Alexa, for example turn on living room tv, get an acknowledgment from Alexa harmony hub light won’t blink. Reset SmartThings hub and harmony hub same result
I don’t use Alexa so won’t be much help I’m afraid.
Doesn’t work thru the SmartThings app either
Step back from the problem, then test a layer at a time.
Does it work in the harmony app? (If not harmony problem)
Does it work in st? ( If not probably networking problem, check your harmony IP hasn’t changed)
Does it work in Alexa? ( If it’s only from Alexa, then it’s a connectivity issue between Alexa and st)
Not working in SmartThings. Checked the ip address of one hub and it is the same no change.
Check the Harmony skill in Alexa app. Maybe it is logged out.
