I got a Iris keyfob for about $5.00. I could pair it to ST hub v2 easily. However, after that, I don’t see any function that I can assign the buttons to do things.
I ended up to use WebCore to assign the logic. I can armed away, stay and disarm by the buttons now. However, it only works for the classic SHM. It does not work to the Samsung Connect smart home monitor.
Thank you very much.
