Alexa for homey doesn't require "tell homey".. google home, pending the update.. honestly my 2 home mini is now used only as a rebro for Homey text to speech.
Honestly, MCO, Aqara (with Neutral), TKB, are all good.. As long as vesternet carries it, it usually means there support from most of the european hubs which is compatible with SG
Same for MCO on Homey, but TedToonBloom is working with AutomateAsia on the Homey support for MCO switches.. so in some way there is local support. The samsung and Yale smartlocks app for Homey are also developed by Automate Asia.
One of my neighbours is using it. It's toggle switch like the aqara, but slightly more responsive on zwave than Aqara on zigbee..
