I started migrating from SmartThings a couple weeks ago. I hit the SmartThings max devices limit in SmartApps and couldn’t take it anymore. I’ve only got about 5% of my devices migrated so far. I have around 425 so, a ways to go. I’m using WiFi, Zigbee, and Z-Wave devices on Home Assistant, no issues so far. Things are very different. A lot more flexibility but you have to spend a little more time figuring things out. I miss webCoRE, but I’ve moved onto using Node-RED to do my automations with Home assistant. I recommend…
GoControl Zigbee + Z-Wave Combo Stick - So far zero issues, great range.
