Can you please tell us what type of wall button you have connected to this opener? Also what is the firmware version (Konnected project version) on the Konnected device?
Yes, the purple-button openers do respond to a dry-contact trigger. The purple button indicates Security+1.0 protocol which also responds to a dry contact trigger.
Thanks for getting back. Control panel is 398LMC with lift master M3585CS 3/4 HP Garge opener.
Working with HA through ESPHome2025.3.2 and project version is 1.4.0.1
In addition to sporadic opening (infrequent) the HA logs show continuous updates for the following:
lights on/off,
Locked/unlocked
as well as obstruction detected/cleared.
These logs show up almost every 5 minutes.
