I’ve been running Home Assistant for about a year now and always installed every update as soon as it’s released and never had any issues at all.
Yesterday some time in either the zwave js 15.6.0 or core 2025.6.0 update (I am too complacent and did them both in quick succession without testing anything) I lost my Zooz 800 zwave controller. Reloading HA didn’t bring it back. I had unplug and replug the Zooz USB stick and then reload again.
Not a big deal, just sharing FYI.
I’ve had to hard reset my controllers (both Zwave and Zigbee) a few times now, haven’t really found a cause but it’s usually been around times when updates were applied. It almost seemed to me like the device wasn’t released by the old container and that needed a hard disconnect to force it. IIRC logs just showed a generic can’t connect to device error but no sign of what had the device locked. First time I did some investigation, the few times it’s happened since then I just unplugged and reconnected the usb device, restarted the container and it worked after.
I haven’t had it happen for a while at least.
