Z-Wave devices unreachable, but do work


I’ve got a few Z-Wave devices. They all seem to work but some have Flags with either ‘unreachable’ or ‘secure, unreachable’.

Now this is not true because they work, and therefor must be reachable, but what does that mean? Is it something to worry about of should I adjust something?

When I send a test frame it also says it is not reachable. But a basic off / on works.

For clarification:


The devices probably send the “ok I received your signal” too late, or homey processing them too late, or not receiving them at all.

If that is (too late) for 3 times it will sign the device as unreachable, or from 1 time of the “test” button. (this is only for mains powered devices)

Might be a range issue, or something else drastically lowering the range capabilities of those devices.

The basic on/off from the dev pages doesn’t wait for the ok signal back, only for if the zwave chip inside homey gives it the “signal send” state.


For with the ‘wasmachine’ I can imagine it’s out of range, because that’s on the 2nd floor and homey is on the groundfloor, in the 1th floor there is only one Z-wave router. But it does report back power consumption so all flows do work.

For the ‘heater 2’, I can’t imagine its a range issue, I think there is a max of 5 mtr between the heater and the Homey. The Quooker is in between of them, but doesn’t get routed through. Same goes for the PlayStation 4, it’s in a line of sight and I think it’s like 6 mtrs away.

Any advise? Maybe resetting the Z-wave network?

Now there are a lot of different routes… But Heater 2 doesn’t respond anymore. Maybe there is a signal problem, but it is so close.
