This messed with me forever. I fought with this thing when the UI Add-on became available, then it started to work (I didn’t know why) so I stopped asking and used it for months. (Both Add-ons were installed, I thought both were needed).
Then I had to do a restore, and I couldn’t get Zwave up. Again fighting for a while and it worked. Still didn’t put it together.
Finally I recently took a deep dive and figured out what was happening.
If I leave that box checked, IT installs that Add-on for me. How kind #%#$#%##!!
That checkbox REALLY needs to say what leaving that checked does, if the intention of the existing message was to tell user that this installs the ZWave JS Add-on, it completely fails.
This may have been a cool thing when there wasn’t a ZWave JS UI Add-on, but now it’s very bad.
And I’m not the only one, either. Here is a Discord Forum post where the User, Anna, is having the same problem.
Can maybe this be fixed, clarified, something?
