Hi,
I was in contact with the nello Team today. It was about the integration of nello into home Assistant.
They told me, that the integration today is handled by a request of the activity feed, which only is send every 30 seconds. Thats why the bell_ring event is so slow.
But since july 2018 there is a Public Webhook API Link.
I‘m not capable of programming this.
Can someone create a new component which works with this API?
Edit:
A day after I opend this thread, the customer service of nello opend an issue on github by themselve.
It would be great to get this integration!
