When I first added all my Fibaro ZWave devices to my Homey (at the time I had a 2016 Pro), they were added securely.
I had problems with the Homey being sluggish sometimes.
At the time Athom (luckily) shared their source code for apps on GitHub. So I downloaded the Fibaro-app and updated the driver.compose.json for each device:
"zwave": {
"includeSecure": false,
...
}
Following this guide I could install my updated Fibaro-app and re-add my devices. After that, my Homey felt like a different beast.
Everything felt noticeably smoother compared to before.
Anyway, maybe this isn’t the case with the new Homey Pro 2023.
