I am using the MQTT Transmission module to transfer data to the and external system. We have some boolean tags that rarely change, maybe once every 2 months, but it is important that a sparkplug B message with that value is sent a least once a day. I do not want to rebirth since our MQTT Transmitters can have up to 200,000 tags causing a pause in the other rapidly changing tags.

Is there a way to manually force a single or a few tags to be sent via python scripting? The function system.cirruslink.engine.publish() could work but I feel like that would be clunky trying to manually create a matching payload.
