Energy dashboard not showing battery charge/discharge

Configuration
,
1

I have a Solis inverter and a Seplos kit battery (JK balancer, Seplos BMS). The Solis has really coarse (1kWh) energy total measurements over Modbus which creates sudden jumps in the battery totals. To fix this, I’d like to pull the readings from the Seplos power monitor into HA’s Energy Dashboard and use an integration on the instantaneous power (Watts) to get the kWh totals.

I’ve put this together in config.yml and while I can add the integral sensors to the Energy dashboard, it doesn’t show the battery charging and discharging. The values appear in the history view, and Energy Dashboard configuration seems happy (no errors) but if I use the integration sensors, the dashboard itself shows no energy in/out of the battery.

I’m having to define the integrators in the YAML because the Energy Dashboard won’t let me select a Helper as a measurement source.

What am I doing wrong?
