MQTT + Smart things. mqtt.publish works, switch configuration doesn't

Hey all,

Couple of days in and about ready to go on a killing spree. Got & smartthings chatting via MQTT & bridge.

If publishing a packet via /dev-mqtt or /dev-service no bother, on and off my lights and switches go

  "topic": "smartthings/Lounge2/switch/cmd",
  "payload": "on"

For some reason the same doesn’t seem to work for my switches

  - platform: mqtt
    name: "Lounge2"
    state_topic: smartthings/Lounge2/switch/state
    command_topic: smartthings/Lounge2/switch/cmd
    payload_on: "on"
    payload_off: "off"

using mosquitto_sub it seems the trailing /cmd is being stripped. No idea why, or how to get around this. Googling till i get unnatural search bot checks. Where am I going wrong? Any insight?

For anyone who does stumble on this this seems to have resolved itself in the latest beta, so odds are it is/was an issue with 0.86.4. Fixed by shifting to:

hassio ha update --version=0.87.0b0
