HEOS Software is complete garbage almost to the point of fraud.
Beyond frustrated with HEOS, and from reading other posts on this sub it's essentially the same issues everyone else has. They sell expensive hardware with almost completely useless software. The *only* HEOS feature that is reliable more than 50% of the time is Spotify Connect, which is probably just because it uses Spotify software instead of the completely useless HEOS app.
I have one HEOS-enabled receiver (Marantz 6014), and two HEOS Links. All 3 are connected just fine to WiFi, because I can connect to them with Spotify Connect most of the time.
However, anything requiring the app almost never works:
* When I attempt to group speakers, I get a generic "The rooms could not be grouped" error. Most of the time, at least. Like everything else, the result is subject to how HEOS is feeling at that particular moment. * Most of the time when I open the app, it sits at "detecting devices" *and doesn't find any*. So even though I can connect through Spotify, the app is unable to find them?? It's WiFi, not exactly new technology, and your app can't find a device on the LAN? The solution to this is usually just to wait a few hours and magically they'll be back even though nothing changed. * When I try to use the app to play Soundcloud through a device, even though I'm connected to my soundcloud account and can use the HEOS app to browse my SC playlists, when I actually hit play it sits for a minute before saying it can't connect to SC. The solution to this is to just try again 3 or 4 times and eventually it works. * When I first bought the two Links, *neither* of them were able to connect using the built-in WiFi connection. They both detected my WiFi network, then timed out trying to connect, so I had to connect via a wired connection to update the Wifi information. Then after repeating that several times with each of them they eventually decided to stay connected without the wire.
Does anyone actually have a positive experience with HEOS software? If the only way I can connect is through the Spotify app then I may as well have just bought bluetooth adapters for my speakers.
Oh, and I should probably mention that I emailed Denon with my initial problems shortly after purchase, and *a month later* got an auto-generated response saying to read the FAQ.
