Nooooo. Heavy on resources. SPMC is the way to stay on the lower end boxes. Just watch the versioning, some older chipsets (rockchip) were dropped so you have to stick down with 14/15 http://spmc.semperpax.com/
And if you have a WORKING harmony set already. Edit the key layout file to your custom :D
Yep that’s the one. Running SPMC on a Sony Android ‘smart’ TV.
Can these addons be configured for use on the TV hardware itself? (Ie I’m not running a separate android box)
