Limits on Network ID's

I recently added some virtual devices. To keep them separate from physical devices I started at Network ID 100 (0x100). Later on I remembered the max number of Z-Wave devices is 232 decimal. The virtual device seems to work but am I forcing something I should not?

I don't think it makes a difference with virtual devices. I started a 001A, went to Z and now I'm at 002N

@SmartHomePrimer,

Thanks. So I'll keep with my 100, 101....

Don't you think you, as a human, will get confused?

The ZWave USB Stick has no idea about numbers in the Hubitat DB. The Stick will just pick the next number and you don't need 100 devices to cause an overlap, just a few that you pair a dozen times :slight_smile:

You can Include/Exclude the same device quite a few times waiting for it to be correct. That certainly happened to me with the Secure Only devices I have, a lock and a garage door opener. I burned through 8 of them figuring out what didn't work.

The ZWave stick will cruse through its numbers and then wrap, filling in previously Excluded numbers.

If you look at the Hubitat generated ID values for their "virtual" devices, like Lutron or Hub Link, you'll see they prepend some chars. "Ra2" then P for Pico, I presume, so "Ra2P-2-2" for the first Pico in my system.

I'm currently working on an EtherRain Irrigation driver and it needs a Virtual device. The name I gave it is "ethrain" In other words, I don't try and have ONE list of IDs for virtuals, I give each virtual a human (me) comprehensible name. Mostly that's useful when I sort on that column in the Devices page.

@csteele,

Thanks ...... I think I understand now, and maybe the underlying reason. My guess is that because virtual devices are only a software entity and not a Z-Wave device the network ID is somewhat meaningless. It would not surprise me if the Network ID for virtual devices is never used by Hubitat except for sorting.

John
it's just to provide uniqueness
I name all mine the same as the label without spaces

e.g

Virtual switch name: Andy Home
Network ID: andyhome

That way I never have two the same and I don't have to remember what number I'm up to
