MQTT problem

Configuration
1

hi .
i have HA 0.75v with mosquitto broker on Ubuntu server 18.
i have a 10 sonoff device connect to my network . all work fine .
but when the mosquitto service restart , the turn off devices randomly . sometime he turn on some devices…
i can’t found the problem…
best regards…

The problem might be that when the mosquitto service restarts, all devices have to reconnect and therefore any topics with the retain flag set will be sent.

If you restart the sonoffs (without starting the broker), does each sonoff turn off/on consistently when there hasn’t been a command from HA?

If you connect another client to the broker and subscribe to all topics, what does it display? For instance

mosquitto_sub -t "#" -v

i did what you said…
so strange…look the commet that i wrote between line from result.

I think the first message in this sequence cmnd/Kitchen/POWER (null) caused the status to change. The question is what caused this message to be sent. The fact that it has no payload may be a clue, but I don’t know enough about your system to help.

Do you have any automations that send MQTT messages?

hi…
yes. i have automation that check state of all switch.
