Turning off switch briefly reports it as back on in homeassistant, before showing off [question]
I've got a Zooz ZEN15 power switch for a high-wattage device. When I turn the device off via homeassistant, the device's state flicks back to on.. and only some seconds later goes back off. If I look at the zwave2mqtt logs I see this:
z2m:Mqtt Message received on zwave2mqtt/5/37/1/0/set +1m
z2m:Zwave zwave node 5: changed: 50-1-2:Electric - W:4.692 -> 0 +2s

I'm guessing what's happening is hass sends the mqtt message to set the device to off. Homeassistant then refreshes the state of the device, and sees that it's still on -- or that the persistent state is still on (I need to go actually look at the physical switch to see how quickly the device responds). Some seconds later, there's a zwave timeout, and then the switch finally responds with the new state. Note that the power draw went to 0 watts within 2 seconds, so I think the switch actually responds fairly quickly; just the state doesn't get communicated.
I'm fairly new to doing zwave through mqtt -- I'm not even quite sure where to begin here. Any suggestions would be appreciated. Thanks!
Have you set the qos in z2m?
I saw similar behavior in hass with my aeotec dual nanos, they all started behaving a lot better after setting z2m config for mqtt to retain and qos 2.

QoS is set to 0 and retain is enabled. I saw in the z-wave log that there are some timeouts from this device; will dig into that too.
@vvuk Also keep an eye to: https://github.com/zwave-js/zwavejs2mqtt. It's very close to a first release
