MQTT Discovery - manual adding - after ha restart entities greyed out

Configuration
1

Hi All,

I was trying to add all my switches using MQTT discovery. So they come nicely into integration with their own section:

Below 2 examples of 38 in total. When I add them they working great!!!
But, when I restart HA the switches are still there but they greyed out. I can’t use them

Only when I do same thing as first execute the command below they become working again.
How can I prevent that, so they will always work when restart HA?

mosquitto_pub -h 192.168.100.23 -u myusername -P mypassword -p 1883 -t "homeassistant/switch/meek_balcony/config" -m '
{"name": "balcony",
"state_topic": "homeassistant/ha_switches/balcony",
"command_topic": "homeassistant/ha_switches/balcony",
"unique_id": "14685093-ad68-4e03-a978-6fb858e34390",
"device": {"identifiers": "meek_switches","name": "Meek switches","manufacturer": "Peter Oudenes"},
"optimistic": false,
"retain": true,
"qos": 1,
"payload_on": 1,
"payload_off": 0,
"state_on": 1,
"state_off": 0,

mosquitto_pub -h 192.168.100.23 -u myusername -P mypassword -p 1883 -t "homeassistant/switch/meek_bathroom/config" -m '

Don’t use that. That option retains the command, not the state, and can lead to unexpected results.

Mosquitto option -r sets retain flag

mosquitto_pub -r  -h 192.168.100.23 -u myusername -P mypassword -p 1883 -t "homeassistant/switch/meek_balcony/config" -m '
{"name": "balcony",
"state_topic": "homeassistant/ha_switches/balcony",
"command_topic": "homeassistant/ha_switches/balcony",
"unique_id": "14685093-ad68-4e03-a978-6fb858e34390",
"device": {"identifiers": "meek_switches","name": "Meek switches","manufacturer": "Peter Oudenes"},
"optimistic": false,
"retain": false,
"qos": 1,
"payload_on": 1,
"payload_off": 0,
"state_on": 1,
"state_off": 0,
"icon": "mdi:nintendo-switch"}'

So if I understand you ok remove the “retain”: false and leave the -r?
Or remove both?

Leave the -r, that makes the auto-discovery messages retained, so HA finds it when reconnected to the mqtt broker.

You want the discovery messages retained, not the command.

Let my try that. The Retain flag for state will be given by the device that use the topic?

6

Retain flag for state must come from the device.

7

When I check with MQTT Explorer all lines are gone after HA disovered it.
So the retain is not working?

8

Try publishing with mqtt explorer. There is a checkbox for retain.

When I do the -r and retain: true then everything is working ok. After restart the entities are there and working

mosquitto_pub -r  -h 192.168.100.23 -u myusername -P mypassword -p 1883 -t "homeassistant/switch/meek_balcony/config" -m '
