At the reboot of homeassistant I get in log that advice:
Source: components/generic_hygrostat/humidifier.py:354
Integration: Generic hygrostat (documentation, issues)
First occurred: 08:11:12 (3 occurrences)
Last logged: 08:11:48
Unable to update from sensor: could not convert string to float: 'unknown'
And in effect hygrostat card is missing also target humidity:
If I move the blu circle target humidity, I can re-read target hum.
I know the issue is a slow update from MQTT, but, how can I prevent it?
Set the retained flag on whatever is sending the mqtt message.
That way the last state is stored in the broker and when home assistant starts it subscribes to the topic and receives the last message stored in the broker.
Added.
It has retained (restarted HASS and got previos values instead of “unknown” on view card) but… hygrostat got same issue:
