When i had a lott on secure, i would get, for instance, temperature, but not lux.
So no, to many devices on secure, and Homey just misses stuff and slows down heavily.
After many years experience, my serious advice would be: Befour trying anything else, re-include (some/as many as possible) devices non-secure. If than problems persists, take further steps.
But for me, and many more, there were enough topics about it in the past, secure was the big deal: Homey cannot (or could) effectifly handle to many secure zwave devices.
I had issues with devices when i had 20 secure. Now i have a little over 70 zwave devices, about 10 secure. Everything works “perfect”.
You can add different devices non-secure.
A few years back, Fibara could be unsecurely added by selecting the Walli-socket-thing, and it would add the correct item (always tries that) but unsecure.
But now-a-days, most devices from Fibaro are automaticly added as non-secure(!), this to resolve the issue with to many secure working modules.
I know this topic is marked as revolved, but nevertheless want to add it is just a trip down memory lane for me. I’m still struggling with the same issues. I have a mix of 57 Neo Coolcam, Fibaro, Heiman and MCO Home, about half battery operated and the other half powered.
Devices became unreachable, not always coming back after a test or healing. Some devices were reachable but did only show status unreachable when sending a test. Also, the same devices reported movement but no lux or temp (even though the interval value was the same), or reported motion but not the end of the motion trigger. As a result, you guessed it, lamps were unnecessary switched on for hours.
I specifically noticed that the router function of the powered devices of Neo Coolcam lately is doing a poor job, because they are not always providing the router function (and for that reason a lot of unreachable battery-operated devices became unreachable).
I already enlarged the antenna on many Z-Wave wall plugs and this seems to help some bit, but the problems nevertheless persisted.
I had 3 other tryouts in mind, but haven’t had the time to do them.
Completely reset Homey to factory settings and then restore the latest backup. However, I wasn’t sure if this also reinstalled the Z-Wave or Zigbee and other devices. If not, It is a hell of a job because all flows would be broken as well. In that case, I wonder what the use of the backup is (and Why am I paying for it). Maybe someone already tried this?
Reinstalling all devices as unsecure. However, I don’t know what security risks are involved in doing this and also, which devices are to be reinstalled. Devices are currently displayed as “Secure (x)” and “Secure (S2 (Unauthenticated))”. Are these all secure or not?
No, x means not secure. S0, S1 or S2 means secure:
I would just use homey with unsecure devices, well for the most part.
My garage and other key stuff is secure, but not lights or switches.
And i have 70 devices, about 15 i see as secure, and this way, it works fine.
I Also have a modified antenna.
It would still be kinda hard to switch your lights (unsecure). Unless someone really wants to get you, but if you’re personally targeted, unsecure lights would not be my worry; a lawnmower or other devices give plenty of ways to access the netwerk itself, giving way more access then your lights.
My zwave mesh works well and it is very stable. I can not see dependency between number of jumps and secure or not secure. I am quite happy when I see a lot of jumps because it means I have a redundant mesh and a lot of alternative routes.
