How to use the switch binary in the broadcast for both true and false?

[apella12]

Unlike the other command classes, I only see these that turn the device on (true). How to turn off (false?). Tried clicking again, but still true

This is a genuine bug, not a usage issue — thanks for the clear report and screenshot. 🙏

Root cause: On broadcast/multicast (virtual) nodes, zwave-js exposes every value as write-only (a broadcast’s state can’t be read back). Z-Wave JS UI rendered every write-only boolean as a single fire-once button, and that button is hard-coded to always send true. That’s correct behaviour for genuine momentary triggers (e.g. Indicator Identify, Meter Reset), but Binary Switch targetValue is a real two-state actuator, so it should be an On/Off toggle — hence there was no way to send false. Other command classes (multilevel switch, color, …) aren’t affected because their controls don’t depend on the readable flag.

Note the same limitation applies to Basic CC on broadcast/multicast, not just Binary Switch.

A fix is on the way that restores the actuator-vs-trigger distinction so Binary Switch (and Basic) show a proper On/Off toggle on broadcast/multicast nodes, while genuine triggers keep their single button. I’ll link the PR here.

Fix opened: #4751 — Binary Switch (and Basic) now render a proper On/Off toggle on broadcast/multicast nodes, so OFF works. Genuine momentary triggers (e.g. Identify, Meter reset) keep their single button.

Wasn't sure if it was a bug or I was missing something, so opted for the discussion option. Thanks for the fix !

not landed yet, I need to wait for @AlCalzone to come back from vacations to discuss about it as a better fix may be to change something on driver side

Any update on this?
