Shelly EM Power (kWh) always zero, but wattage (kW) reading fine - why? - Configuration - Home Assistant Community

I installed a shelly em in my garage consumer unit yesterday. One clamp on the garage supply, one on the specific circuit for the car charger. Added it via the standard shelly integration. I see the realtime wattage sensors working fine, but the kWh sensors are always zero. I know i could set up a hass utility sensor to log the kWh myself, but shouldn’t the shelly integration that provides the kWh sensors be working? Do i need to do something to make it work? Thanks!
