If you switch to Bulb Energy, they have an integration with Samsung SmartThings - https://bulb.co.uk/blog/were-partnering-with-samsung-to-help-you-get-more-out-of-your-smart-meterWe’re partnering with Samsung to help you get more out of your smart meter.
Although, after having had Bulb fit smart meters this morning, the only data I have available via the SmartThings integration in Home Assistant is the electricity used so far in kWh - not the current power usage in watts. And there's no value for the gas used (yet - I think the Chameleon display hasn't managed to connect to the gas meter).
I don't have a SmartThings Zigbee hub btw - however I don't think the Bulb integration needs it, as it pulls the data from the cloud.
