I added my Roku TV successfully via the UI and am able to select source/power on off, but not set the volume. Here is a complete log and the error I get when I try. Any ideas what to do?

Nobody?? Seems pretty basic for HA to be able to control a Roku TV 
Hi.
Ive been working on the Roku integration as of late.
I would encourage posting an issue on the core repo as itll notify code maintainers of the integration and likely result in prompt resolution.
Ok so Roku TVs only support volume_up and volume_down rather than volume_set as the Roku ECP API doesn’t provide the current volume level or ability to set specific levels.
That said there was a bug that predated my involvement where volume_set support was flagged as available when it really wasnt which is likely a cause for the error.
The good news is HA 110 will include a fix which also helps the way the media card offers control and if you want to control volume by alexa or such since itll know to provide the +/- volume controls rather than slider
Hey @dinobyte217 makes sense, I did know there was no way via the API and +/- does make more sense, but I thought I saw somewhere (perhaps an unofficial integration) that they had hacked it so basically when you adjust volume, it always goes to 0 then up a certain number of steps. It’s a hack, but it would be nice if this was “coded” and invisible to the user. I have my TV start when I get home and i’d like to preset the Volume.
I’ll post on the repo, but I wasn’t sure which was the “official” repo, can you share a link?
I can say the slider bar is now gone, but I preferred it in a way. I think it should be hackable to set volume by going to 0 then up to desired set-point.
I have an issue with my Roku TV (TLC) where volume down and volume mute just fine, but volume up does not. If I use the native media card, the volume up works. Any idea why volume down and mute work here, but not volume up?

@jjwBullfrog why use remote. vs media.. IMO using remote is like using SENDKEYS in VBA, it’s hacky and should be avoided. Using the “native media card” talks w/ the API (I’m fairly certain). Was hoping @dinobyte217 posted a link to the Github URL here, but perhaps it should be reported there as he advised.
