Sorry for the slow response, I haven’t as been as active on these forums as I used to be. I need to get back into it.
This is one of those remotes that was so rare that we didn’t migrate it over yet. It turned out to be a quick task though, and we’ve just prepared it for the next beta release. I should be able to get a beta version of the firmware that supports this remote to you tomorrow.
You’d need to use the beta app to get this firmware, details on getting that set up can be found here.
