Server version for Raspberry Pi 4
I cannot install the current .deb package. Raspberry Pi is armhf, not amd64.
The server app needs to be cross compiled for arm. I don't know if @rivafarabi has the time or a raspberry pi for testing, so unless the sources are open sourced (#222) this is unlikely to happen. Nevertheless this is a great request because additional to providing a arm build, a headless build would be awesome too. That way you could use Deckboard for home automation applications or trigger webhooks (IFTTT and similar)
arm version might arrive, thanks to the Apple Silicon.
That being said, I'm pretty sure that deckboard is an Electron package, hence it should be quite easy to compile it for Raspberry.
Android version is built on flutter... Using that for arm might be the better route.
