I am building my HA and planning to use some Zwave (smoke/co alarm as it is the only one approved here in Canada) and water leak sensors using Aqara Zigbee. My initial thought was to buy a zigbee/zwave USB stick to do so then I found the Sonoff Zigbee gateway which is flashable with Tasmota. The wifi gateway is a better option as it allows me to put the gateway closer to the nodes. I am now looking for smoething similar for Zwave. Any ideas?
