No Data after Core Update or Supervisor restart

[LaCruz75]

There are no data from rtl_433, when a core update was performed or supervisor was restartet. Only reboot host helps.

Interesting, I've done several core upgrades in the past few weeks without issue.

Is the problem that updates aren't making it to the mqtt broker, or that home assistant isn't reading or connecting properly to mqtt?

ok, I turned logging in for rtl_433, there seems data come in. So the core restart issue belongs to the addon "rtl_433 MQTT Auto Discovery"
After manually restart this addon after a core restart, data come in.
So, how to fix that?

Do you have mqtt_retain turned on in the auto discovery addon? If not, that would explain it.

[LaCruz75]

havn't set mqtt_retain..
If that is need, why is standard not true?
I had no idea if I needed that.

Thanx for your help.

I'm actually not sure why it defaults to false. It was added over at 41b6e03 but that doesn't explain the thinking behind it.

I'm not sure it's completely "required". For example, I think with a device that sends updates often it will get reregistered quickly. If it's longer, such as a door sensor that only updates every few hours unless it's opened, it may lag.

What kind of sensor were you trying to read, and to confirm flipping that setting worked?

Let's change the default at https://github.com/pbkhrv/rtl_433-hass-addons/blob/main/rtl_433_mqtt_autodiscovery/config.json#L16 from false to true to finish up this issue.
