What model numbers are you using? Are they Z-Wave Plus?
FWIW, here is what I use:
light.family_room_lamp: refresh_value: true delay: 4 polling_intensity: 1 light.master_bedroom_lamp: refresh_value: true delay: 4
light.family_room_lamp is a model 12718 Plug-In Smart Dimmer, which is not Z-Wave Plus. I found I need both refresh and polling with this device.
light.master_bedroom_lamp is a model 28167 Plug-In Smart Dimmer, which is Z-Wave Plus. I found I only need refresh with this device.
Note that the
delay is set to 4 (seconds) for both because their default turn on/off transition time is around 3 seconds.
