I have been scouring this forum but so far have yet to find a solution for this problem.
Using the Aeon Z-wave stick on Raspberry Pi3+ with Hassio install.
Z-stick is recognized and appears under configuration but when trying to use the add node button, it does not add any device and the error “Can’t lock controller for command : add_node” is logged under the info section.
Any help on solution to this would be greatly appreciated?
For me the issue was related to adding z-wave devices that were previously paired to a zwave controller. I had to make sure that I excluded the zwave device before adding it. In some cases, I had to factory reset the zwave device that I was trying to add.
Thank you. Just moved to new Hassio images, and then factory reset all my Zwave devices. Now I have Sonoff switches that aren’t appearing – believe that is MQTT related.
