Maybe this is impossible or undesired but I recently happened to stumble on a GTV-BT1 remote on amazon. I thought it looked nice and purchased it to control my Sony TV.
So far I have been extremely impressed with the build quality, range and ease of bluetooth pairing. It wasn't until recently that I realized the remote is sold to control Formuler devices and can't be customized on a non-Formuler device. I am wondering / hoping it is possible to install the Formuler Remote app on a non Formuler device as I think it is an exceptional remote that can be used for a large number of devices.
