I have a Arlo Doorbell. It could connect to an existing doorbell - but unfortunately, I just have 230v there and not even both poles - just the “plus” that can be connected to make the existing bell sound.
My idea was to put a zigbee device behind the doorbell, that let’s me know once the contacts are connected. First I tried a aqara water leak sensor. But it shows wet as soon as it is connected to both contacts - so the resistance is too low.
Do you have any other ideas how I could make this work? is there a device that is specificly created for noticing closed circuts?
and yes… arlo sucks… no mail notification, no doorbell notification in IFTTT, Aarlo integration in homeassistant only works very spotty (not their fault…)… So I need a workaround
It’s an arlo doorbell. It is designed to also slow-charge from the connection - that’s probably why.
But as they do not have a usable api and not even the google home integration is stable, I was trying to hack around this. But hey… since it now does not even work with google home anymore - I’m probably not going to invest much time in this … … …
Could you use a modified door/window contact sensor? If the current is that low anyway, I’d think bridging the reed sensor with your push button would make them show open/closed.
