I run HA on a NUC trail has 3 USB ports. Currently 1 is a Google Coral for frigate 2 is a HA Connect and 3 is an Aeotec ZWave stick. Recently the failing Aeotec. M queI got a HAzwave upgrade to replacestion is will I run into any problems if I temporarily disconnect the Coral to connect the zw2 and set it up and then move it to where the Aeotec was and then plug the Coral back in? Are power cycles required’? I would like to avoid reinterviewing everything.
It would mostly depend on how you set up the sticks in the frigate & Zwave configuration.
If you set them up using something like /dev/ttyUSB0, then that is subject to change if you unplug/replug devices. However if you set them up as /dev/serial/by-id/, then you shouldn’t have any issues.
The following is from the ZHA docs, but it applies equally well to anything which requires a USB device to communicate
You might not necessarily run into issues if the devices set assigned the same path when you plug them back in, but at the very least take note of what paths they are using before unplugging anything.
I think you misunderstood what I asked or maybe I said it wrong. The coral will only be temporarily removed while I plug in and transfer everything fq the Aeotec to the ZWa2. Then I will unplug the ZWa2 and plug the coral back in and unplug the Aeotec and plug ín the ZWa2 where the Aeotec was. I don’t understand why the hardware address of the Aeotec or the coral would ultimately matter.
Nope, I understood perfectly.
Any time you unplug and replug a USB device for whatever amount of time, you run the risk of getting a different (USB) serial path. The only way to ensure this doesn’t happen is if you use the device path.
