Unstable zwave devices!

Configuration Z-Wave
1

Hello

I have a HA Blue with an Aeotec Z-Stick 7.
I use Z-Wave JS.

I have a problem with some of my Aeotec ZW078 Heavy Duty Smart Switch.

The temperature sensor or consumption sensor come offline very often and after that it is the all device.

I have a good zwave network with some devices to extend the signal.

I need to heal and reconfigure the device several times to make it work again but for how long ?

I absolutely never experienced that with my previous box (Homey), perfectly stable zwave devices.

Any ideas ?
Thanks.

No idea ???

Could you please clarify, is this device the first one to fail and the rest “breaks” as well? Any logging you can supply or how the device is configured for reporting?

I learned the hard way that 1 bad device can crash a network. Check those logs. You may have a bad Z-Wave device causing headaches.
In my case, I believe it was flooding my network and the hub at the time (Vera) couldn’t handle it.

I have two Aeotec Heavy Duty switch and they both become offline very often.
To get them back online i need to restart my box or sometimes the all inclusion process.
This is so enoying, i never had a single problem with my previous box…

and is the HA blue in the same location that your previous ZWave hub was? Is the Aoetec stick on a USB extension cable to move it away from the HA Blue?

Everything is in the same location.
No USB extension cable.
I have other zwave devices with no issue at all.

And i loose them again…

OK - so now we need to know how far away from the Stick these devices are.

You are comparing a commercial product that has passed Certification and testing to perform the function of being a ZWave (among other things) coordinator. Versus a USB stick which depending on where it is placed could suffer from interference from other things surrounding it - which is why people suggest the first troubleshooting step is to stick in on an extension cable to get it away from sources of interference - mostly electrical interference from the USB port it is plugged in to.

ZWave is a pain to troubleshoot because the stick is doing the work, and the stick decides when a node is dead. The stick decides a node is dead after a number of failed communication attempts, and once the stick has decided a node is dead - there is nothing the software talking to the stick can do, to change the stick’s mind. Either the “dead” node sends some sort of transmission and the stick marks the node as temporarily being alive again, or you soft reset the stick (NOT a factory reset).

Why it is only about the Heavy Duty devices ?
I have zwave devices before them and after them in my house.
None on battery so they are zwave host.

ZWave doesn’t work like that - it is a mesh, until we can see the mesh we don’t know what path communication is taking.

Why is it only those devices - well there could be something manufacturer specific that they are doing that Homey had a fix in place to work around.

Or it could be how they have been included? Are they using any sort of security?

No secure inclusion and all my zwave are Aeotec : the zstick, heavy duty, multisensor 6, aerq, siren, etc…
Where can i see zwave path communication ?
I will include them back but it will failed again in a few days i’m sure about that.
