I always use xmpp to send notifications via webhook. Now I would like to test matrix. I installed the integration and it works to send text messages. Unfortunately I can't send pictures (png). what am I doing wrong?
@boebbele
Glad you solved it.
I learned there was a homeassistant matrix integration by reading your post and tried it bit could not make it work, I always have an authentication error.
Did you use the core integration or did you use one from hacs?
Also do you use matrix.org or a custom matrix server?
