ZEN77 (and other three-way switches) not mirroring traveler and load state when “Smart Bulb Mode: Enable/Disable Paddle / Z-Wave Control” is set to disable local control.
This means that when local control is disabled and the load is set to off, things behave as expected, but issues arise when the load is set to on. In this case, the traveler seems to still be set to off, rather than mirroring tbe load state, resulting in a load that can be switched off by toggling the three-way switch.
I think there needs to be a firmware update to fix this errorneous condition so that when “Smart Bulb Mode: Enable/Disable Paddle / Z-Wave Control” is set to disable local control, the load and traveller should be mirrored such that if the load is off, both are off and both on when load is set to on.

Hi @Waka324 ! The ZEN77 (as well as the ZEN76/74/73) cannot be wired in a 3-way and used in Smart Bulb mode. The above models all have a unique patented design which was specifically created to allow for installation in 3-ways without needing to rewire the second box. However, this also means that these units rely on current readings from the load to change and maintain status; therefore, they cannot be used in multi-way installations with smart bulbs. You would need to use the ZEN72 dimmer here (or the ZEN71 or ZEN32 models).
