Most entities are unavailable after restart of Homeassistant

[daninden]

When Homeassistant is restarted, most AquaMqtt entities appear as unavailable.
This is probably due to the mqtt messages not having a retain flag, so they will only get available again after aquamqtt sends an update for a particular value.
Was this a design choice? or is this a bug?
Is it possible to give them the retain flag, or alternatively send a message to aquamqtt to update all it's values (send from homeassistant on start).

Hey, this was actually a design choice. Certain values are retained, e.g. totalEnergy, while others are not retained since they are bound to the time, such as powerTotal. A retained value of totalEnergy is always true, since it was the latest value seen at the broker. Retaining powerTotal for example does not make any sense, e.g. AquaMQTT is not online or has wifi reception issues or whatever....

But, there is MQTT_FULL_UPDATE_MS which causes a full update of every MQTT topic. You may want to decrease that to shorter value. For example, sending full updates every minute instead of every thirty minutes. This should resolve your issue, but of course you will see more updates within homeassistant.

AquaMQTT/AquaMQTT/include/config/Configuration.h

Line 83 in 2cbcb17

constexpr uint32_t MQTT_FULL_UPDATE_MS = 1000 * 60 * 30;

Edit: Triggering a forced update via MQTT, should be very easy to add. I might look into that, but I am currently quite busy with other stuff. So don't expect that to happen soon.

thanks for the quick reply!
I will try changing MQTT_FULL_UPDATE_MS to a lower value, see if that takes away most of the 'pain'.
