IHD Firmware release 1.8.13
I am currently rolling out the above SMETS2 first and later SMETS1
Here are the headlines
Fixed stack overflow on local MQTT task which triggered a restart
Modified local MQTT gas meter JSON to remove export and power and added to the import field: cumulative, day, week, month volume, cumulative volume unit of measure and day, week, month volume unit of measure.
Modified local MQTT device state JSON to add the wifi MAC
Adjusted local MQTT publish events to be as close as possible to 10 second intervals
Added workaround check for gas meter calorific value and conversion factor values that are not marked as invalid but which are clearly wrong. Added checks for calorific value, conversion factor and CO2 value attributes invalid values specified in SEP 1.4.
