When I create a MQTT switch using mosquitto_pub on the console, it gets kind of 2 buttons instead of a single toggle button.
The result looks like this:
instead of this:
What am I doing wrong?
Without knowing how you defined your switch, difficult to say.
One remedy could be
The command is like this:
mosquitto_pub -h $addr -p $port -u $username -P $password -t "homeassistant/switch/SW_test/config" -m "{"name": "SW test", "command_topic": "homeassistant/switch/SW_test", "unique_id": "some_SW_test", "device": {"identifiers": ["Some device"], "name": "MyDevice", "sw_version": "1.0"}}"
Adding “optimistic”: true like this
mosquitto_pub -h $addr -p $port -u $username -P $password -t "homeassistant/switch/SW_test/config" -m "{"name": "SW test", "optimistic": true, "command_topic": "homeassistant/switch/SW_test", "unique_id": "some_SW_test", "device": {"identifiers": ["Some device"], "name": "MyDevice", "sw_version": "1.0"}}"
doesn’t change anything nor does adding a state_topic.
There is a command topic, but no state topic. HA can’t know the state of the switch, hence the 2 buttons.
Thanks. Unfortunately adding optimistic or state_topic doesn’t help.
mosquitto_pub -h $addr -p $port -u $username -P $password -t "homeassistant/switch/SW_test/config" -m "{"name": "SW test", "optimistic": true, "command_topic": "homeassistant/switch/SW_test/set", "state_topic": "homeassistant/switch/SW_test/get", "unique_id": "some_SW_test", "device": {"identifiers": ["Some device"], "name": "MyDevice", "sw_version": "1.0"}}"
gives the same result.
Does the state topic effectively return the correct state ?
As long as I don’t set anything it’s “unknown”. But meanwhile I found the solution: setting the command_topic and state_topic to the same value did the trick. Thanks for your input and ideas!
