I switched from a Pi 3b+ to a Pi 4. I restored from a snapshot. I updated my configuration.yaml to reflect the new path to my Aeotec Zwave stick (it’s now /dev/ttyAMA0) and edited /config/.storage/core.config_entried to reflect the correct path. When I start Hassio, I get 2019-12-13 16:54:52 WARNI…

Yup. It’s connected directly. I’ll see if I can dig up a USB 2.0 hub! Thanks.

Whew. That did the trick. Thanks so much. For anyone else stumbling across this one - make sure you update your YAML to point to the new tty port. It’s possible that it changed when you introduced the hub. If you use a path like: /dev/serial/by-id/usb-xxxx-xxxx-xxxx It shouldn’t change on you. …

Help! Can't reach Zwave after reinstall!

Did you connect your stick to a USB 2.0 hub or directly to the Pi4’s USB port?

If directly, there’s a known hardware issue with the Aeotec stick where you need a USB 2.0 hub to get it to connect properly to the Pi4.
