Hi Peter,
Thank you! Yes, this solved it. Leviton dimmer module polling interval default was 10000 (ms?). I changed it to 20000 for all units, in Homey, under the settings for each device (Leviton app installed). Zooz switches do not have this capability to change polling interval apparently. All Z wave devices are now responding very quickly and consistently. First time since I installed these that I’ve had consistent response. Thanks again!
