I’ve seen posts where a recent version of HA has broken the ability to send notifications via the HASS_Agent. I found this link Bug: Latest HA Core update 2024.5.0 breaks notification entities. · Issue #2 · hass-agent/HASS.Agent-Integration · GitHub.
I removed the original integration from HACS. I then installed the new custom repository. It never rediscovered the Windows computers but the devices still showed up in MQTT Explorer under hass.agent. Do I need to delete them from here and if so how do I accomplish that?
