Is this normal and expected behavior? If I use hubitat to set dimmer to 99 with a duration of 900 the slow fade on works great, but notifications get ignored during the 900 seconds. Not sure which gen I have of the dimmers, they used to be called reds. so gen 2 maybe? z-wave.
This is just a guess, but a change of illumination level will temporarily override an active notification. Is it possible Hubitat is sending level changes frequently enough that it’s completely stepping on the notification?
