Running Homey 1.5 here with:
- 30+ z-wave devices (various plugs and buttons)
- 70+ zigbee devices (mainly Ikea, and Xiaomi some hue and innr)
- 100+ flows.
- 20 apps
I think everything is fairly snappy and never really notice any major lags (see disclaimers below).
The UI is pretty slow but as I use it mainly for automation I never use the Homey app to control anything (the 1.5 app is horribly slow with many devices as it paginates and do not cache).
The other issue I have is with zigbee and that is most likely due to how it is implemented as all commands are sent one-by-one so clicking a zigbee button which turns on 3 lamps and change the color will take several seconds (but this takes several seconds without many devices as well).
