@Ari thanks. Got the replies.

Considering there must be an API, as you have an iPhone & Android App, it's a tad disappointing you won't make it available.

Can you please develop a Homebridge plugin for the H2, maybe using the Sony TV (Android TV) plugin as a base. This way we could control the H2 Projector like a TV from HomeKit.

I want to integrate to Apple HomeKit, using HomeBridge, as a TV service. is there an API?

I can screen mirror just fine. However, when I use the AppleTV application on my iPhone (iOS 13.5) it fails and I get an error on the H2.

Anyone had any joy?
