Proscenic 790T Integration

Hi there! Please, excuse me for any mistakes. English is not my native language. And currently it is 4:04 AM in Bulgaria. Yes, yes … You’re right - Bulgarian is my native language. And PHP. And Swift. Anyway … It doesn’t matter. I just finished Proscenic 790T platform for the vacuum component. Tested! It works well. One advice - If you’re making custom card, please use the ‘vacuum.proscenic_*’ services instead of the default. There is a reason for them to exist and why you should us them instead…
