I have a few questions: 1.In Homey Developer Tool, when I display devices in the z-wave network, two devices are visible as Offline. The devices are working properly. Why are they shown as Offline? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/5/050c311c5ea264fca5968b3d35a346254de58451.png) 1. Why is the “Remove” option not available after selecting the device? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/e/3e36ca26ced24dce224e6ae883857ad8da28b8fa.png) 1. What does the “RESET Z-WAVE NETWORK” button do? Is this used to rebuild the Z-Wave network? ---

> [@Grzegorz](#): > > RESET Z-WAVE NETWORK No it resets your z-wave network to factory defaults. So you can start adding devices again. ---

Have a couple of Zwave battery devices myself, and they have always been offline. Worked just fine since installed. They are just sleeping/saving battery, and only wake up every 15 min to report sensor data. ---

What is the difference between your 2 “multisensor 7” devices, as shown in your picture? 1 runs on battery, the other on mains? ---

The “wake up” time for most battery-operated devices is only few seconds long. In order for to be displayed as “online”, the DevTools page would have to be refreshed during this short time. My recommendation: do not worry about it. > [@Grzegorz](#): > > Why is the “Remove” option not available after selecting the device? You have to delete Z-Wave devices via smartphone or Web app. The “Remove” option in DevTools is only active if the device no longer has a connection to the Z-Wave network or is an unknown device/NodeID. ---

There is a trick to make “Remove” option became available. Just click on “Test” option first, and “Remove” will be enabled 🙂 ---

This shouldn’t actually be the case if the Z-Wave device has a stable connection. I’ve just clicked on “Test” 10 times, but “Remove” didn’t become active. If the “Test” fails, then “Remove” is activated, that’s right. Tested on HP23 ---

I checked it on a several battery powered devices, and it always work, as the battery powered devices cannot respond on demand. And like you said, it will not work on non-battery powered devices, if this device has stable connection. ---

Yes of course, this works with battery-operated devices because they cannot send test data to Homey if they have not been woken up first. So in this case they are not reachable for Homey. ---

So why not perform a backup of Homey Pro, then factory reset the hub, then install the backup?
