Polled message BuildingCircuitFlow does not reach MQTT

[twslocombe]

With the current version (and previous version) 20260607 the message hmu.BuildingCircuitFlow does not get sent to Home Assistant via MQTT. The value populates when a read is triggered manually.

This reading is important as it is used for the emoncms heatpump heat calculations.

Thanks

please check the log tab (also by using the "follow" mode) for polled messages and share the output of the REPL command "nvs_get poll.08". And what is your poll interval?

Hi, exec: nvs_get poll.08 198801 [image: image.png] Poll rate is every round (~91 seconds). I don't see any errors regarding the BuildingCircuitFlow in the log (attached). Thanks, Tom

there are no logs in your comment.
Also I can't find anything wrong with the polling in my environment.
anyway, I'll add more verbose output when a poll is started to the next release, so it can be tracked more easily

this is a matter of the message definition that apparently has the wrong unit associated. so please check https://github.com/john30/ebusd-configuration/ for that one
