Wondering how to get the Z-Wave working again. This is about the only reason to have home automation. I powered down the HA Green in order to acquire updates, and this is the result.
“Failed setup, will retry: Invalid server version: Z-Wave JS Server version (3.1.0) is incompatible. Update the Z-Wave JS Server to a version that supports at least api schema 44”

HA OS, so the Z-Wave JS is an add-on. Can’t you update the add-on ?

How do I assure that I have the latest version? There’s no indication that an update is available within the OS, while the GitHub is confusing.

Aha. I need the update, but how do I find it? The OS doesn’t offer the option.

Almost there. Thanks for your valued input. I installed the Terminal & SSH addon, but when I run the command, I get this error:
“Error: addon zwavejs does not exist”

Could be, I don’t have it installed myself
2 ways to find the correct slug
ha addons
gives a list of installed add-ons, look for slug: xxx with xxx something like zwave
or go to the add-on page
the slug is the text between /addon/ and /info
replace zwavejs with the found slug
ha addons update zwavejs

Many thanks, Francis! That did it. The add-on is now at 0.21.
