Without knowing details of your unsuccessful attempt, or what exactly your goal is with the integration: from OpenCPN you can directly send APB or RMB messages to the Raymarine tiller pilot, which should enable the tiller pilot to follow the 'route' that is activated in OpenCPN. You don't even need to have OpenPlotter functionality for that. I used this before I had pypilot and this is still operational for backup purposes. In theory, you could plug in a USB-to-RS232 interface into a Raspberry that runs OpenCPN (e.g., openplotter) and tie the TxD to the NMEA+ of the tiller pilot; practically you should do this with an electrically decoupled cable, as anybody else will advise you. With my ST2000+ compass somewhat calibrated and after some messing with the variation, this gave me a max crosstrack error of about 0.04 NM in calm conditions, which is better than nothing, and it might be what you want.
