Monowave HKZW-DWS01 keeps going offline

Another week and offline again… Does any one have a solution for these Monoprice Wave Plus contact sensors (Model HKZW-DWS01) that continue to go offline…

Are they really offline or are they just marked offline? Easy to check. Just open the door or window and see if they respond.

If they respond they are really on line and changing the wake up intervale might help.

If they don’t respond they are truely off line and you may need more repeaters.

These all worked for the last few years before moving to Edge drivers and the 2 that it keeps occurring to are within 10 feet from the hub. I have tried setting the timeout to 30 and unable to get the parameter to update. After using the config driver and the “Send” action when I use the “Get” action it shows 0.

If the wake up interval is still coming back as 0 then the device is never doing its wakeup checkin and will show offline once its inactive for a period of a few hours (exact duration is unknown, but likely 6-12 hours).

When using the Config Mc tool to set the new wake up interval, you’ll need to wake up the device in order to get it to read the new setting. From the manual for this device:

A default wake up interval of 0 sucks, and the stock drivers don’t override this value or allow you to change it so it makes sense that these will keep showing “offline” within ST.

If you’d like we can add support for the device on the Zwave Sensor CS driver. The wakeup interval is adjustable within the driver and will have a sensable default applied. What is your device fingerprint (viewable on the Advanced Web App under ‘manufacturer code’). Is it 0208-0200-0008 or 0208-0201-0008?

Thank you, below is the information.

Manufacturer code:

They also dont report battery status properly. I can put new batteries in and they show 15%.

@csstup can you confirm if this has been updated in the driver?

Not yet. It will be a few weeks.


I thought my battery had finally died after 4+ years, turns out it was probably still going strong, just the EDGE driver and now ST reporting it offline. It does report once the contact status changes. The battery last reported around 30%. What a shame. It was probably fine.
