The Open Door works. The Ring to Open doesn’t work and I don’t get notification when someone rings. I called the BPT support and told me that the slot 4 (RING) doesn’t give electric current (12V) like other intercoms, it works with audio signal. Is there a way to get the Ring working with the audio signal? Do I need a different set up?
This means it gives not enough current to trigger the opener. You would need something, what amplifiers the current to a value high enough to trigger the opener, when someone rings.
I have similar problem. The opener works in terms of opening the door by the app but it doesn’t ring or open when someone ring the intercom so I can’t have the ring to open feature. The bell is connected to 2 and 3 of the interphone. Someone could help
