Harmony hub I was able to control it from HE since I set it up, I had a power outage because of the snow. I confirmed the Hub IP is still the same via the Harmony app and it's the same in HE, but when I tell Alexa or manually click in HE it says it's turned on or off or Alexa will say "ok" to turn it on or off but nothing happens. I'm at a loss as to what else I can do, it's nothing being reported in the log either. I can use my Harmony remote with the Hub and it works.
Check the ip entered in Hubitat matches the ip that your DHCP has assigned to your harmony hub. (located via your router) It's best to assign a static ip address to it.
It's crazy that I was looking into this and what's crazier is that the Hub in my router had a difference IP that it was showing in the app on the phone yet the app on the phone allowed the hub to work. I ended up having to force close the app and clear the cache and now it's showing the right IP in the app also. I made it static now. GTG.
