[Solution Below]
How do I get this energy calculation to calculate new values every half hour so that the hourly Energy Dashboard bars properly reflect that hour’s energy consumption rather than the weird spikes I get once every day. There should be an energy jump 07:00-08:00 am and another 14:00-15: 00 and a couple more later on
Although I had read-through the forum for similar issues and fixes it was quite a lot to consumer and unclear if the issue was related and the fix generally accepted.
Anyway:
Not using MQTT Integration but set up the plug on MQTT anyway - I imagine the MQTT broker add-on is required. The devices are integrated with the Shelly Integration
Previously unavailable Shelly firmware upgrades were then available - so installed those
