Hi everyone so I got my google Chromecast tv (with remote) to work now.
As noted from a previous post, set your VAVA projector so that it boots up from HDMI 1 (or whichever port your chromecast is in). This way you wont ever need the vava remote again.
When setting up your chromecast remote, use the “Panasonic” settings. It doesn’t matter if the volume/power doesn’t fully work, just finish the setup.
When you’re in the chromecast OS, use the chromecast remote to go to settings > Remote & accessories > Setup remote buttons and in here make sure the “volume” and “power button” settings are set to “AUTO CEC” and not the panasonic default.
This should make it so your chromecast remote turns on/off the projector and control volume.
