Hi again,
Just if it helps someone.
I have a few simon 100 io integrated in home assistant as follow:
1.- Get a z-wave hub (aeotec z-stick gen 5)
2.- In home assistant go to addons and install z-wave JS
3.- Go to settings / devices and services / add integration / add a z-wave device
4.- Click center button of the simon io device 2s<t<10s and release
5.- If everything went well, the you can see now the new device
The only problem I have is with some master io shutter that doesn´t get any configuration from the database or wherever.
