I have a problem with HASS and OpenBK because sometimes MQTT packets are lost and HASS remains with a different state than OpenBK.
HASS automations don't send again the signal because the behaviour is optimistic, OpenBK doesn't send an update regarding the status because it isn't changed.
Is there a way to implement a sort of QoS or a heartbeat from OpenBK that updates HASS about the status every xx minutes?
Thanks
Which MQTT broker are you using, and what are your current MQTT settings for this device/topic (especially QoS, retain, and any persistent session/clean session setting)?
mosquitto, default in HASS.
I enabled 'Flag 7 - [MQTT] [Debug] Always set Retain flag to all published values' to avoid undefined message on OpenBK reboot
I also enabled 'Flag 35 - [HASS] Deactivate avty_t flag when publishing to HASS (permit to keep value). You must restart HASS discovery for change to take effect.'
What exact OpenBK device/firmware version and Home Assistant MQTT entity/config are you using, and do you already have any periodic telemetry/state refresh/availability option enabled?
