Hi.
I'm using Z-wave for 2 years now. have about 50 devices in my 3 floor house. The road so far has been very interesting but also stressful and certainly not set and forget job. The conclusion is I would never dare to install Z-wave to any non system admin person that has no ability to act instantly when **** happens. It only takes one device for fail.
Other thing is I have heating and power management done using HS. So failure of a system will lead to:
1. people freeze in winter days
2. people have saunas in their rooms
3. Peak protection (turning off non-priority devices) fail could overload house input and provider will cut of the supply.
Those are serious issues. Is the design of Z-wave up to the task even when everything set up properly. Does the protocol allow for that kind of reliability?
So the main question that comes to my mind are the following.
- Communication between device and host . Many times values are not updated properly or actions missed.Battery devices will send out signal on state change. Then is sleeps to save the battery lifetime. So what happens when the signal does not reach the host. Is there any bidirectional communication for host to approve the signal received? How can it happen quote often that HS devices are not updated with real state of the devices. Where is the catch? In the device, host, communication data???
- MESH
Mesh seems like a good option to extend the range, but is really OK? What happens is one device in MESH fails? Will that cut all the devices that is using it as a gateway. Would it be better to set multiple receivers (let's say one for each floor or how many it needs) and have it communicate
- ? Device Icon
Many times I get ? device icon. It always scares the **** out of me. Sometimes it corrects on next update, sometimes it does not.
So after 2 years of dealing with HS, I can really say it's a great platform, but really not reliable and makes me scared of using it in demanding operations. Needless to say Logs are great, Z-Seer+ test on all devices are 100%, but **** happens anyway.
So the question is. How to maximize Z-wave reliability for reliable serious tasks with bad consequences on failure, where status update of the device must never be missed? Is Z-wave even up to it?
Thank you
